I have noticed this to be a trend with some tuners/programmers. There doesn't seem to be anyone that have found a solid fix for those having the issues.

Please try to refrain from bashing products, companies, or people, I'm just looking to get some numbers on how many people are having the problem. There seems to be a number of happy people, but then some that have had a lot of problems with the same tuners/programmers.

Also, if you previously had a tuner giving you the P0087 code, please vote and reply.

Thanks! :)

I have run 2 of the tuners listed above and not had any issues with either one. Are you also looking for year specific? Motor specific?

I have the PPE hot+2. Only time i have had this code was after the race valve install.. Thanks to all the guys on here I found out that I just needed to really tighten the S out of it..since then no codes!!!!

I have not seen this code on mine.

I run PPE and never have seen this code

I had the code on my truck when I was running the Edge/Attitude on level 6 "Hot". I found the cure to be a good lift pump setup. Since then I have had no problems.

Think it needs to be broken down into the regular lower HP tunes and the "race" tunes. Also lift pump and no lift pump. Also codeing dosnt show a rail issue. I can suck my rail way down.....but when it gets pissed off it seems is in the higher gears when it down have a chance to spike the pressure up on gear change(and thus reset the timer for setting the code, thats my theory anyway)

Try running out a program you dont think codes up to 110 or so. Then see if it codes. Or log the rail pressure or just look at it with a scan tool like the PPE.

I can code with the PPE set to kill right at around 105. under that or just flogging it it may run less rail overall but it still wont code. It dosnt code normal or beating it up on the street or even ussualy at the track, just when i do a high speed run.

I chose PPE......I have also done it with EFI live numerous times....but have backed the fuel down to were it dont do it. Most times with my own tunes it would do it on a higher speed run as well and not outa the hole.

I run PPE tunes and have never had this problem. Also never had it with the Predator I ran before that.

I only got mine when I tried the Speed loader setting, and every level after until I disconnected my batteries for 10 Min's. Now it's been almost a week with no further problems.

PPE, had 0087 in the hot tune. Than put in lift pumps no code. I upgraded to the hot +2 and now i get the 0087 code. Any ideas for this code.

You may need to do the shim mod, just a thought.

if it is the code for low rail pressure then i have gotten it once on the hot tune.

I have ran the PPE on 90HP,and no code.

Shim probably wont do anything. Take a look at this thread........

First time tripping p0087. Im running the Edge with juice on level 5. I gunned it around the corner untill i hit about 65 then i fell flat on my face. I turned around ,stopped to make sure I was clear to get back on the road and headed back home not knowing if I broke it and the truck would not go over 25mph or so. So I pulled over reset code good to go. Is there a cheap fix?? Or what is the fix? Thanx

I have ran the PPE on 90HP,and no code.Got one this weekend at the drags with the 225HP tune. Temperature was around 100 deg. In cool air seems to be fine.

If you have lift pumps and an aftermarket turbo and still get the code you probably should be looking for a secondary cp3. Definitely not a cheap fix. I am in that boat now. I run out of fuel on the top end. Low hp tunes should never throw that code.

If you have lift pumps and an aftermarket turbo and still get the code you probably should be looking for a secondary cp3. Definitely not a cheap fix. I am in that boat now. I run out of fuel on the top end. Low hp tunes should never throw that code.Higher elevation, combined with high fuel temps will surley cause a p0087 on our trucks. If you place fuel under enough vaccume it will boil at room temperature. Up hear our fuel is under about 3lbs less atmospheric pressure than at sealevel due to our 3lbs less air pressure. Also the heat makes the diesel fuel less viscous, which makes it harder for the cp3 to maintain PSI. Like how your oil pressure is less on a hot engine. A secondary fuel cooler may the guys getting the code while towing.

Very good point. I think the DA at bandimere touched 11,000' on saturday for a short period. It was 9600' most of the day sunday.

Seems like every time I hook the sled it throws the code and goes into Engine Limp, I have a fass stand alone, and the shim, still does it. It will do it on the street too if I really get into it hard:mad: Yet too have a full pull because it always goes into Limp around 270:mad:

You've got EFI. Make a tune that doesn't drop rail pressure too much.

Wow, for all the Banks bashing I saw in various threads the Poll results only show 5 problems. Surely Banks has sold more than 5 tuners. Looks like other Tuners are having the same problems.

anytime you add more power then the fuel system can keep up the computer shuts it down to 2k rpm's so you don't blow the injecters,now i found a cheap fix that helps for everyday driving and most times when pulling and it is the PPE FRSV kit but really to do it right you will need lift pumps http://www.pacificp.com/index.php?main_page=product_info&cPath=2_7&products_id=53 the LLY does the same thing only it is a 1057 code..hope this helps
ps i did the PPE kit on my LBZ and haven't thrown the code since and thats runnin the PPE HOT +2 on the high setting..

I don't think the FPRV is the issue with the LBZ. It was an issue on the LLY becuase the rail pressure would spike, either when lifting off the accelerator or during a shift, and the FPRV valve would blow open allowing the truck to dump rail pressure and set a 1057 code. I don't think this is the issue with the LBZs. I, along with several others running large tunes, have stock valves and haven't had any issues, but everyone I know of who is running a big tune is also running a lift pump.

If you want to do a shim or race valve I would at least do a bottle test before you do anything to it to see if it is blowing fuel out.

thats what everyone told me but i had a shim kit on hand and what can i say before i had the shim kit i had the code 4 or 5X but since only once and that was at 120mph racin a Turbo Fuel Injected Firebird but other then that no problems but i plan on the lift pumps for this winter..just my thoughts..

I limped every time I got on it in 4th or 5th gear I installed a SD lift pump and and it has'nt happend a single time since then, I have a shim kit in the glove box I hope I can leave it there.

Ive been running my truck around for about 2 weeks on PPE 350hp and havent had any codes. Im sure its only a matter of time, but Im surprised the code hasnt come up yet, its not like Ive been driving it easy..Tomorrow Im heading to the drags so im sure thats where it will come up, and Ill have to turn the power down to reality.

Run it out to about a buck ten at WOT. See if it limps then

i get the oo87 code often, im running ppe level 6 ( 350 hp ), fass 95, ppe shim kit. if i run the 225 setting i never get it. sure would be nice to get this problem solved.

what about the ppe ported fuel fitting?? do you guys think it would help??

I got my first 0087 code today hitting 110mph. Just like everyone else I was wondering what the next step would be? I realize that this most likely wouldn't happen in a 1/4 mile run. If this continues to happen does it weaken the fuel pressure relief valve after each limp? Im aware of dual cp3 pump but isn't that going to wipe out my pistons or rods. Thats a lot more fuel being thrown in and not upgrading the rods a pistons makes me a little nervous. This is uncharted territory for me.

I have seen it twice. Both times I ran WOT and after the code, replaced the Fuel filter. I cut both filters open and they where solid black. Seems to be my time to change the filter indicator light. Especially since the DIC read over 50% both times. I think next mod is a Nictane.

Yeah maybe I have to break out the hacksaw and give the filter a look. Nick tane might not be such a bad idea either. I dropped down the PPE to level 5 and seems to run smoother with less smoke.

I only throw the 0087 when truck pulling lately never did until the last to pulls of the season. I can be into it hard up to and past the 110 mark and not get it to code so i don't know.

okay guys i have a 06 LBZ with the PPE tuner and anytime i run a hot tune such as 160hp tune and bigger i was getting a 0087 code with a hard throttle and on the lower tunes it would take longer and then when i downloaded the 350hp tune it would only take about 5 sec.s of a WOT and i had a 0087 but i fixed my problems and this is what i did,lift pump and i have had her all the way up to 130mph runnin the 350hp tune and nevr kick in the 0087 code so if you want to run hp tunes you will need a lft pump and the one i'm runnin is the PPE lift pump but any 90 to 150gph pump will due..

Shoot Dan@PPE an email or PM or phone call

The code pops if its below a certian range for a certian period of time. When you shift it will spike the rail up and recover only to be drug down. Your not in the lower gears for long and its not a long constant load. It is at the pulling track or on a long high MPH run.

LOG THE RUN OR AT LEAST WATCH YOUR RAIL PRESSURE ON THE TUNNER! Otherwise your guessing if you do or dont have an issue. Then do a bottle test if you think the reliefe may be blowing off.

So I guess that i'm the only guy thats having problems, even with a lift pump. Maybe the TTS pumps aren't able to keep up since the first pump kicks on above 28#s of oil pressure and the second kicks on after 18#s of boost. So what im trying to say is maybe the pumps would be able to keep up if they were on all the time like the way kennedy has his pumps on all the time. Or should I just ditch this setup and try a single 90 to 150gph setup?

It seems mine is very picky about the fuel filter. It is starting to set the 0087 code again and has been about 6-7,000 miles since last fuel filter change. Guess im due again if im gonna be hot rodding it. Just towing on level 3 i still have no troubles. Only on high Hp and on long blast big mph runs...

My TTS pumps keep my rail pressure up just fine, and the second pump kicks on closer to 10 psi of boost on my truck.

PPE tells you to change fuel filter I think every 5k miles, I do mine every 3500 to 4200 with oil change.

Damn that would get expensive in a hurry. : (

Maybe the PPE hot+2 is just to much for a single cp3 with a lift pump on level 6. Its pretty ironic how you tend to find this out after you buy the hot+2, and realize you have to upgrade to a twin cp3 setup or you can't run level 6 efficiently. At this point with the twin cp3's your risking a bent rod or melting a piston.

I do just fine with the ppe lv6 and gt4094. I really dont like twin pumps think it would work better with 2 pickup points. also its is ahame we could meet up think George said you got hung up getting crabs or something

Mine through the code last week. Changed the filter and all is good. Try doing the bottle test to see if your fprv is week. Also I've read on here in another thread that a member posted where some lbz are having problems due to the fprv not seating properly due to the fuel rail. Then it's causing the p0087. I belive it was in Haulin-Rv's thread before he sold his lbz. They stated after a new fuel rail the code was never set again. Something worth looking into.

I just got my first P0078 today. I changed the filter 3 weeks ago and have been running mostly mild tunes. I ran the McRat race tune for pulling and the Diablo tow tune yesterday for towing a 30 foot camper, but mostly stock and stock today when I got my first code. I was pulling away from a stop going DOWNHILL taking it easy and it coded. 2000 rpm limit until I got home. Cleared code and would set again as soon as I got to 20 miles an hour (even easy footing it). What I can't understand is my last filter was on for 10K and when I cut it apart the filter media was 90 percent discolored (which is normal), this time the filter media was imaculate colorwise with no signs of debris, but the filter element looked like it had acordianed (i.e. sucked in). I will take a picture and post tomorrow.

I took it to the dealer (nearby and open late). They put the gauge on it up by the intake and it was reading (in the words of the mechanic) "terrible". I put a new filter on ($25) and rechecked the gauge. It read 3psi which is where he said it should be. I bought an extra filter to keep with me as I have a vacation and tow trip this weekend.

Those with P0078's should check your filter EVEN IF BRAND NEW. Mine was less than 3 weeks and 1000 miles old and terrible inside.

On a side note, the filter was the old white one and I replaced it with the new blue one.


Technical question: On a stock truck, does the fuel suck through the filter or is it pushed through? The reason I ask is I have no lift pump and was wondering if it was due to the CP3 trying to suck the fuel through during high demand?

Thanks!

Josh, unfortunately due to the following pics, I could not do the testing I said I was going to do for you.


Keep in mind this filter is less than 3 weeks old (as you can see it was not dirty, but it was severely distorted). It was a little worse than this, but I was checking in between the pleats to see if there was any junk, so in the process I helped straighten it out some :( :eek: .

That doesn't look good, is that normal?

i haven't had a 0087 for 2k miles and the whole time i was runnin the hot+2 on the 6th setting and the highest speed yet is 120mph and then yesterday all of a sudden it did it so i was kinda ticked but ended up my lift pump quit so i bought dual lift pumps for it..

What lift pump did you have? I just changed my fuel filter and it really seems to run better. Only had prolly 6,000 miles and was all Black inside. : (

Our LBZ has not thrown an 87 yet. 16k I think, all under big tuning.

I run Edelbrock 1792 pumps and EFILive tuning.

EGR blocker
EFILive tuning
Mike L / Suncoast Trans
Cognito's and SD sleeves
Edelbrock 1792

My fuel rail and air box are stock also, the lift pump seemed to solve my 0087 problems. I have a shim kit in my glove box and was just waiting for my next limp before I installed it. I hope I can leave my shim kit where it is.

I think its in the programming that the HOT +2 gives so much extra fuel demand compared to the EFI.. IMO

It seems like most guys getting the code, myself included are only getting it at wide open throttle after a full 1/4 mile pass and still on the pedal till about 110 or better on level 6. But running on level 5 on the hot +2 I have yet to throw a 0087. Sunday I ran an 03 lightning with a tune exhaust and pulleys till about 115 and no codes, 3 cars ahead by the way, the lightning owner was a little upset. He kept on saying how he just put down 400 rear wheel at the dyno shop, LOLOL, and couldn't believe how strong my truck took off out of the hole. Sorry about the thread hijack But I figured you guys would get a kick out of my sunday afternoon.

how fast is your truck in the Quarter with the mods that you have and how do you like the lift pump that you have...

Mine will set that code also after a long full throttle run on Level with both pumps running at the same time. This Sux!

Im not sure yet what i'm running. Me and a bunch of friend rented Atco NJ racetrack for Oct 29th so I guess I will find out then. Im hoping for sub 13's or real high 12's. I like the set up of the pumps, but with the PPE hot+2 on level 6 The lift pumps aren't able to keep up. I don't think any lift pump can keep up with the fuel demand of the Hot +2.

mines a ok up to around 130 mph on lv6 and 1/4 turn on maximizer

I used to get them a lot with my edge on hot so I shimed the PRV and I dont have any more p0087's I also added a lift pump to but that Isn't what fixed my p0087's.

just around 135 before I lowered it some, started floating around to much.

how many shims is every one running mine will not code taking it up to 120 but will code when pulling the sled. The seasons all done so i have to wait to next year to try out any thing else.

I'm running the race valve.

race valve or get the shim kit and drop 3 to 4 washers in instead of 2 like they suggested..

Stock valve with 0 shims here. No problem holding rail pressure.

JoshH how do you like the co pilot? Do you have to reset it after a hard quarter mile run, i heard that there's still a couple of bugs to work out for the copilot on the lbz's.
