I have basically the exact same set up as pdiddy but mine is a L99. With the stock 3.8 pulleys (for now), LS9 injectors, ZR1 plugs and the stock air box, where should I be for RWHP. Without the Maggie I had a dyno run of 375 to the rear wheels. It's sounding like the LS3 makes quite a bit more HP than the 26 additional that it starts with? Any thoughts.
