When I first put the standard ppe in my truck, it hauled ass. I kinda noticed gradually month by month that it settled down, not goin like it used to. I figured it was just the winter blended fuel, but now after running strait #2 for over a month, it still hasn't gone back to how it was. It runs perfect, no blueish/white smoke. It doesn't seem to put out the black smoke when I step on it like it used to either. Fuel mileage has seemed to go down as well. I change fuel filter out religiously. So I'm thinkin now that possibly it is the programmer. Has anyone else had this happen with ppe? Is it even possible that it could be the programmer?

Since PPE writes the tune to the ECU, nothing will ever change about it unless you change the tune again. More than likely, you've just gotten used to the power and now you need more!

it kinda feels that way too me also.but i think i just got use to it

Well, if thats the case.. I need more!

Thats the way it is. HP sucks. You never have enought. Time to build the trans and step up the tune.

These guys are speaking the truth...
I had a tune on my truck for awhile, and then after awhile I couldnt even tell it was on there. I went back to stock for a few days to make sure it took and it felt like a dog.
A DOG, this is the truck stock that would bring a smile to my face from a stoplight or on the freeway at will... LOL

x2 put her back to stock for a week...then load it back up...you'll notice it back then. :)

Trans could be slipping more now than when you started... just a thought.

Definitely a possibility.

Do you think your Suncoast is slipping? I turned my ATS E-Power off the other day and just ran my Banks on SL and it felt like stock to me. It really made me appreciate the E-Power programmer. I only run the ATS on 6.

I'm sure MY tranny isn't slipping. But from the OP's sig he doesn't have a built trans, so slipping for him is definitely a possibility.

Also, the Banks stuff is totally different from the PPE stuff so it's not really a great comparison.

I wasn't comparing Banks to PPE, I was comparing Banks to ATS which is written by PPE.

Gotcha.

I've had my 225 hp tune in for about 8 months, approx 11k miles..still feels the same..I have dropped down to the 160 tunes for a day, it sucked...well not really, but compared to the 225 hp tune, it seemed so slow..Make sure everythings workin properly, if it is..time for more hp..:D

wheres the smoke though?

wheres the smoke though?

Could be a fueling glitch...

Another thought...how's your airfilter..?

wheres the smoke though?

Don't worry about smoke, Hammer's got that covered!

yea ive been curious about the smoke thing... ive been running my ppe on level 4 without a hint of smoke coming about the back, im not worried about it but i figured id be seeing some by the time i got up there

You need to run level 5 to get smoke...:D

I just wonder why his MPG is going down, getting use to the power shouldn't effect the MPGs.

Kevin

Well, if thats the case.. I need more!

HP is kind of like money. You can never have enough! :D

Have you had the injectors replaced?

mine does the same thing, it used to spin the tires more when i roll hard in to it , but i think thats the stock tran ive always run it on lvl 5 and 6:rolleyes:. and the smoke is alot less on lvl5 after about 4 months of being on lvl5 if i what a lot of smoke i need to load up lvl 6, but it still hauls ass i not saying theres something wrong

fueling glitch? lift pump needed, filters, pickup? but programmer should be ok

My Trans isn't slipping, I just put new plates, TC and shift kit in about a month ago, because I had limped it a while back. She is solid that way. Air filter was new around December, and it looks clean, maybe wouldn't hurt to clean it though. The injectors were replaced around 35,000 miles ago, as well as the head gasket. I asked my PPE dealer about a lift pump, and he said I don't need it, that it's mainly for the llys.

i have an lly and just sent it in to dan at ppe for the same reason. Low and behold.... Injectors... Yes iam use to the power but Dan suggested to get some new injectors and what a difference. Not after market injecters just stock injectors. Thanks Dan for always taking my dumb calls.

I would have to agree with the injectors possibly needing replacement. Happened to me. Truck was just slower than it should be, and couldn't hold the rail pressure that it should. Replaced the injectors and had a new truck:D

when replacng the injectors did you have gm replace them or did you by them yourself? becuase its my understanding that gm wont replace all of them?

Well its not the tuner , its doesnt work like that , it cant just go bad . Its a written program to your ecm . You need to start checking things out . For a a start you need to log your rail pressure and see if your draining the rails and not keeping up with pressure . Change your fuel filter again . Maybe your CP3 is weak , maybe add a lift pump . Yes you do get use to the power , but it sounds like you have some kind of a fuel related issue .

You should do more homework before pointing the finger at your tuner .

You need to get a tech2 on there and have someone look at the injector balance and look at your rail pressure at WOT . Do you have the boost valve in the correct spot , do you have gauges on the truck and is your boost the same as usual . There are many factors as to why the truck might not be performing like it should . What is your max boost and is it the same as before .

I would bet you are going to find , lack of rail pressure and it dropping off on long pulls through the gears .

Then there is the transmission ....... yes you could not be getting all the power to the ground like you once did . Converter .... Clutches ...... sliding shifts ... who knows ..

I will tell you what it isnt , not the tuner .

If you had just sent it back for a reflash and it wasnt working properly I could possibly understand . But it cant just change . Its a written file . Same Same

Starting a post saying ppe not the same as before , without doing any homework or posting any useful like rail pressure and injector balance is a bit unfair to PPE .

1. change fuel filter

2. Get some fuel pressure reading at WOT .

3. Check the injectors.

4. Clean your Air Filter .

5. Clean your MAF sensor.

6. Get a boost guage reading at WOT ..... with boost valve it should be around 28 psi if I recall .

7. Call PPE for some help on this issue , they are very good about servicing thier customers on issues like this . And can help you figure out why you are losing power and not smoking like before .

Im guessing lack of rail pressure , and get a lift pump on it . Maybe your CP3 is weak possibly .

Or a bad load of fuel and change the fuel filter and the other things listed as a combo of things causing this .

Good Luck , hope you get this figured out . Being without what your use to on power really sucks .

Post Back and let us all know what you find .

Take care , Johnny

Just so you know, I wasn't blaming PPE. This is my first diesel, and I am pretty inexperienced with all of this, but learning everyday. I was asking if there was any way that it COULD be the tuner. I wasn't pointing any fingers. Sorry for the misinterpretation. Thanks for all the good advice. I'll find a Tech2 and see what we come up with.

Sorry I didnt mean for this to sound chitty . Wasnt the intention .

It was the Title of you post that stuck out on the thread topic listing .

I hope you get it all resolved and would like to help.

Seriously , If I can be of any help PM me or call me , 714-514-3675 Anytime

I know what it's like to be stuck on an issue with the truck and trying to figure it out sometimes sucks .

Injectors .... maybe . But first see if there is a local diesel shop near you with a tech2 to try and get rail pressure readings on it at WOT (wide open throttle). Your tuning is calling for 23,000 psi and if it's falling way down to say 17,500 your having trouble keeping up the rail pressure. Also in your tuner there is a diagnostic area that you can see your injector #'s . They are different than the #'s a tech2 reads but still a good thing to look at to see big differences in injector balances . It could be injectors . But first try to get a look at rail pressure .

You should be able to waranty them if it is injectors . On the tech 2 if you see balances over 3 that is the # dealer requires to replace them . The numbers you will see on your ppe tuner will be 5-6 's . They arent the same as tech 2 . So dont go off the #'s you see on ppe tuner . It is only good for seeing huge differences like one injector being very high compared to the rest . The tech 2 is the one you will see the true injector # on that the dealer goes by.

Good Luck , Johnny

Where would one get a Tech 2?

Phil

when replacng the injectors did you have gm replace them or did you by them yourself? becuase its my understanding that gm wont replace all of them?

Your understanding is correct . Usually they do no more than 3 at a time unless it's a LB7 . On lly,lbz,lmm they replace ones that are out of range .

Usually only a few meet the requirements for replacement on later motors . On LB7 they dont want to do it again or risk a leaking seal and you can get all 8 generally .

But on later motors only the ones out of range get changed

( over 3 on balance rates on tech 2 )

On a ppe tuner your injector balance rate #'s are twice what you see on tech 2 . So dont be suprised when you see 5's on ppe tuner .

I did not know that about the PPE tuner. The last injector I had replaced read 11 on the Tech 2!!! I took it to the dealer because my reading was over 6 in neutral.

My readings on ppe are around 4.8-5.6 last time I looked and on tech 2 it was around 1.7-2.4 . Not sure if its the same on every ppe tuners scan function . But hearing you are reading 6 is close to what I read . The eleven they saw was definately a bad injector though , but what did they see on the other injectors . I was told by a tech that they needed to see over 3 to replace an injector . And he said my ppe must be reading a different # . Were others at 11 ? And when you say 6 , do you mean they were all at 6 pretty evenly and you took it in and they read an 11 on just one injector or many ? Wierd you would think your tuner would have showed that high # . Makes me wonder why it didnt .


I saw a 15 on the dead cylinder when cracked piston and checked with ppe .
And the rest of the clylinders were normal #'s
