Well, I finally got to run the truck at the track. Let me start off by saying I thought it would do better, but not sure what is the problem. I just installed the PPE Hot E.t. today, after running the PPE Hot (330). I made a total of 5 runs at the track. My t-bars were turned down, psi down, 4x4 launch with minimal tire spin/hop, rear leafs clamped. The backdown was disabled on the HJ but still reached 100% going down the track-:t ??? I then removed the HJ (unplugged) and ran with just the PPE and still seemed to "lay down" mid way down the track and pick up power again towards the end. Here are the Censored results:

First run:
PPE E.T. / HJ #1 with no t/h mode
60' 1.922
1/4: 14.550 @94.97

2nd run:
PPE E.T. only with T/H mode
60' 2.038
1/4: 14.56 @ 94.30

3rd:
PPE E.T. / HJ #2 with no t/h
60' 1.922
1/4: 14.47 @ 94.96

4th:
PPE E.T. / HJ #3 with t/h
60' 1.899
1/4: 14.416 @ 95.03

5th:
PPE E.T. / HJ #4 with no tow
60' 2.019
1/4: 14.607 @ 95.57

These are my results. Like I said, the truck went to full backdown a couple times and the other runs it did not show in the "stats". The truck seemed to just lose power at a similar point on the track and then start taking off again towards the end. The trans shifted good and truck never felt like it bursted. The feeling was like a rev limiter coming on slow and going away. All of the filters/fluids are fresh. I am just disappointed. What are your thoughts, besides get a TTS:) . I should have the sd nitrous/ lift pump in my hands very soon, but would like the truck to run "faster" prior to the addition. There was only 1 other cc duramax at the track running low 15's with a bully dog. :help:

WTF is right, I could run that with my reg. Juice.

On Edit: To answer the original question. Most aftermarket diesel performance vendors advertise their improvements in RWHP, because they have no way of actually measuring FWHP. Very few engine dynos in the aftermarket community can generate the load necessary to hold back a turbo diesel engine of 6.0 liters or more at such a low rpm. In fact I know of only one aftermarket diesel performance company that advertises in FWHP and they have no way to substantiate the numbers they advertise with actual measurements. Buyer beware! __________________

Mackin,

Are you trying to say you want to purchase my PPE?):h I should have ran just the HJ/AT, but did not have time. Do you think everything looks somewhat consistant? Like I said, it was my first night out at the track so 60' times are not the greatest.

Seriously, I think those numbers are a little high.

You could shave a tenth or two off your 60 times. What is a level 10 trans?

:exactly: ....never heard of that trans.

Also, was the pyrometer hooked up on the Edge by any chance?

Chain drive

With the edge, the pyro was connected. The backdown was disabled for all runs and also, the edge was actually disconnected from the main harness for 1 run. As far as the trans, I know everyone is only used to hearing about the ATS, SC, etc. The shop that upgraded the trans is called Level 10. Their business is mainly building high performance transmissions, especially for race applications. If I was a trans guru, I would be able to recite everything that was done for the upgrade. I know the list was long, and just about everything was replaced/upgrade/modified. The shop said it would be able to handle 1200hp/1800ft lb. They told me to try and break it, as it has a 1 year unlimited mile warranty. I let them know that I will be trying. Take it for what its worth, but the trans has been doing good.

I just dont know whats up. :help2:

Not sure, but on the LLY Edge with the pyro hooked up, it would back down about the 330mark thanks to the high EGTs. Maybe this also happened on your runs?:confused:

:eek:

That's a mighty big claim by them. What is your,their location? I'm interested

Mackin.. I agree with you, but if I am told to try and break it, I will ):h . I am located in north-west NJ, as is the shop. The shop is at Level 10 (http://www.levelten.com)

Ah Englishtown area,not far from me at all. Good luck let us know if you break it.

Get that wick turned up :thumb:

Teamhertz.........

I ran the PPE HOT Excellerator at Lebanon Valley.........

http://www.dieselplace.com/forum/showthread.php?t=29429&highlight=lebanon+valley

I too posted that the tune layed down on me in fifth..........but I still eeked a 13.3 or so out of it.......

Since the PPE was a loaner from JIM659 and has not been updated I would be interested in seeing how yours runs.........

You have a good transmission and need that fuel pump so I would expect mid 13's from it then.........even my 1.8-1.9~60/FT times still yield 13.15-13.30's on my truck.........

In fact I recently wen 12.99's on my set-up.........;)

Take a ride this friday if your are free............open test-n-tune at Lebanon Valley Dragway in New Lebanon, NY

Here is the thread on it............

I will bring my stock ECM and run the your PPE HOT heads up if you want........see what it does........

Tony,

I am hoping that the lift pump will solve the issues. As far as this Friday, I know I am working nights, but will see if I can get off. If I can, I will be heading up your way. Thanks for the invite and offer to help. I will check the status of the pump and see if I can get it by then too.

Sounds like your running out of fuel to me...

I bet you can watch it on the tech 2 when it lays down, rail pressure will fall out the bottom.

Yep you need a lift pump. As far as I know the only other thing that will cause the Juice to backdown besides EGT is TRANNY SLIP???

I had my doubts about the backdown feature on the edge so that is why I unplugged it, from the main harness, on 1 of the runs. The truck felt the same EXACT way when it lost power running just the PPE. So I am assuming the SD lift pump will solve this issue. The pump and sd nitrous will be here in a few days....cant wait!!:weld:

what was your 1/8 mile time and mph?

what was your 1/8 mile time and mph?

Average for the 5 runs was about 9.2 @ 74.5mph. -:t

my 1/8 times with just the ppe was on avg. 8.5@81 mph.the stack gave me some 8.3's this was without the lift pump,shocks,centerlink and caltracs

my 1/8 times with just the ppe was on avg. 8.5@81 mph.the stack gave me some 8.3's this was without the lift pump,shocks,centerlink and caltracs

I wonder why your truck, for example, was able to run without any fuel issues/modifications? What would cause the difference?

Every truck is different. Some have a lot of fuel related issues, some not as much.

I have athe PPE Hot ET and spent considerable time with it now. I would check with your Tech II and see if you are setting an overboost code also. What is happening is at about 85-90mph if you are hitting around 32psi boost your ECM is going to put you in a fuel derate because it does not want to see it get to 36psi(boom). It will not give you a dash light so use the Tech II and see if yo have a code. PPE says they are working on some way to get the 2-3psi of boost that they want without setting a code. Some early trucks have the boost sensor with a short hose and you can fool it with a bleed tube. Mine has the boost sensor right in the intake aluminum housing and I have not been able to figure out how to "fool" the darn thing yet.

How much was the trans. upgrade?

First check for codes stored. It will code w/o setting SES light. Then talk to Joe at PPE and tell him what happened. There will likely be boost codes present. The Edge being installed can help this, BUT I don't like the timing combination so either a 4.35 Edge is needed, or Joe will have a device to help this. I spoke with Joe about this Friday evening and he mentioned that he had it ready, or at least designed.

I wish Edge had a plug in connector for the pyro leads. My personal units will be modified to include this...

I have never set any overboost codes with my current programming, the PREDATOR when I used to run it would set them all the time...........;) ................probably something that needs to be adressed within the programming.........

I hope to run the newer PPE HOT at the track this Friday to see how it runs compared to the last time I ran one............the lay over was causing the boost to drop considerably in 5th gear at WOT........it really slowed the truck down.

Good Luck.........

I just checked the truck for codes with the PPE. The truck has no codes stored and has not been reset since the track. I did get a dash light at the track to "Service 4WD", but there are no codes for anything. The truck also has the PPE BIV installed. I have only had an overboost code once with the PPE 330HP version w/o the BIV. Should the BIV be removed? Could I actually hit the 32psi limit without setting a code? My edge is ver. 4.83.

Thanks for the help!

$5400

Over and over and over again, my truck will lay down when running the PPE, or Quadzilla big tunes.

It will set a Po238 if memory serves. Running a Juice on 0 will eliminate this.

One thing I'll add is that I've been told by by people that they don't set codes (lly 1093's for example) and hit a limp mode, yet when I re-create the same conditions, the code is found with the Tech 2...

The PPE doesn't seem to be a very good code reader. It will never read 1093's on my truck and the predator will. I have seen this several times over and over again.

I'll set a occasional "silent" over boost code and I know others that do too.Doesn't affect run ability like the other mentioned tuners had done.

Weird to say the least

kennedy is right you need to run the edge to stop the 0234? overboost code The PPE tuner I have is not the E.T but has some timing out joe knows how much with this tune i was able to stack edge up to level 4 with no ill effects(stock charger and injects)best the truck ever ran unfortunatly was never able to test it at the track I was running that tune + edge on 3 with the bigger injectors and the SUPERDIESELcp3 kept the rail pressure where it was suppose to be, this is my favorite tune as it never rattled with the edge and just plain hauled the mail, the full timing extreme tune would rattle even with the edge on 0

Thats funny i just stacked a 330 ppe hot program with my 150 horse edge hot juice with ppe on 330 and edge on 5/5 and it just flat out hauled the mail. stock turbo injectors NO LIFT PUMP STOCK TRANNY ran it 4 or 5 hard times. tranny really didnt even slip. The edge did back down at 76% though. but it never burst. i ran it clear up to 80 or so miles an hour. didnt go into limp mode either

I wish i had a stock tranny like yours, mine never stacked as well as others but seems to run just as good or better then guys who turns thers all the way up. I think it is a individual truck thing.

You guys are good!!:) I had a diagnostic computer hooked up (not Tech II) and these are the codes and names it found:

P0101 MAF
P1093 Fuel Pressure
P0238 Boost Sensor

It looks like it is a combination of fuel and boost issues. You guys were dead on:ro) . Why would the MAF be triggered? I have a swiss cheese box with paper filter. The MAF was also cleaned after the K&N was removed with electronic cleaner.

I spoke with Joe @ PPE and he said, like Kennedy, there will be a device to protect from an overboost code. Should be ready in 2-3 weeks.
