[QUOTE="01yellercobra, post: 17000254, member: 35549"] Wut? I know of builds that ran 11-12:1 with boost on E85. One of my Cobros here is running a built engine with 11:1 and a Whipple 3.0 at 28 or 29psi. He's close to 900hp. I'm beginning to think your tuner might be your issue. Op, what about looking for Mach pistons? I don't remember how much difference there is between the chambers in the 99/01 vs 03/04 heads. But the Machs were 10.3:1 from the factory. Well, thereabouts.
