Congrats Grover.... Your right about where you should be IMO. My car put down almost the exact same numbers when I was running stock manifolds, catted midpipe, C&L maf, & a stock tune... I think my car made somewhere around 280-ish rwhp & 294rwtq.... I think what was costing me a few horses on the dyno was my heavy 18X10" wheels & 295's.... I think with stock 17X8's, I woudlve put down 3-5 more horses...
