So my cutout gave me 40hp. 360 vs 400. So the facts may be that the cut out being on with the Stock exhaust close may be costing me 24awhp. Thanks Ray.... I think. lol

Was it a stock downpipe that was open or a larger aftermarket one? And I just run open o2s lol. And were there pre cats or not?

^^^ Somethig along those lines I though of. How would the system be affected with bigger frame turbos and tubular manifolds?
