I'm seeking assistance I came from the Duramaxforum board with no luck. anyways here is a quick run down of the problem.
stock tune I have decent power, nothing too impressive kinda feels like its not running tip top, but I can still "Power Brake" it for example and spin the tires.
PPE Xcelerator installed I have NO power low end can't even power brake it because it needs to wait until about 2500RPM then the turbo spools up real quickly and takes off shifts through the gears real fast. this entire time I dont get any smoke at all, not even a lil black puff while im waiting for it to spool up with the pedal smashed to the floor. I approach a small incline and I'm screwed gotta drive it manually cause cruise control keeps violently dropping from 5th to 4th spool up shoot 5mph past set CC speed then drops down and repeat.
So far I have Changed the fuel filter, called PPE and they said "Well change it again" and got upset when I told them I just replaced it and it still runs like crap in the low end. I dont have any check engine codes. stopped by the dealer today and had their diesel tech take a quick look at it and he said it sounded normal just runs like a pig til it gets to high rpms. suggested possibly needing a lift pump. however they drove it with the tech 2 hooked up and said everything appeared to be fine, balance rates, fuel pressure got up around 22,000 at the rail. only thing he said was the oil pressure was slightly low but nothing to be worried about.
I hope somebody can help me with this problem I'm desperate!
