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.

Isn't it common for the idc to go crazy high if the pump can't flow the fuel?
If it's not goin up then the pump shoudn't be the issue just a tune issue....?
