Your boost gauge is off, a stock setup on 8psi through an auto 2v would be in the ballpark of 330-340rwhp

O wait on race gas? makes more sense cause as said on pump gas your not over 350rwhp. Might want to mention stuff like that from the beginning. Also that power curve is the choppiest looking thing ive seen, who the hell tuned that car.

It made 396/405 on 91 pump. My boost gauge works fine. The graph looks like that because it was having crazy belt slip. 3.00 pulley with stock rib and tension. Pullied up to 3.25 and its seeing 16psi now.

Apparently not according to this site. I post on SVTperformance, Stangnet, and the Corral....this is the only site that seems to have a problem with my numbers.

Just a quick copy of someone sig on Stangnet:

I know you got a D1 instead of a P1. But I am making 2 more lbs of boost and about 30 less rwhp and 20 less ft/lbs of torque. GFDIt!!!!!
He has a P1, Ive got a D1 and we both hit roughly the same numbers (with me on 91). I hit 396/405 on 91. Pretty close to his.
