Well hells yeah it will. Toss 45 degrees and watch that knock retard haha. I'm joking but really timing can cause det. it's just finding the right amount with the CORRECT Fuel to make it work together and your problem seems to be fuel not timing.

It was mainly just a joke. Right now i'm running 32* just waiting for a unlocked pcm so i can get some dyno time to find the sweet spot.
I know for a fact my truck before the heads at 28* was soso then got it tuned at 33.5* and it was a monster in comparison.
I'm really just wondering how much the y-pipe being a 2.5 on back would be hurting the truck honestly.Oh yeah i do gots me some of dem worked heads hehe.

EFI, I think the pump is maxing out, he has plenty of injector. Now if the tune is off, then that could very well be it, but if the tune is on, injectors are plenty and regulator is good, then the pump is the only thing left.

I know the injectors should be plenty. My point was that if the IDC is way high then it could show/tell you the pump isn't enough. If it's normal levels then it's just a tune issue...or should be anyway.
