i have those mods, cai/im/tb/h/e/no cat/ ecu/vtc afc/ and skunk2 stage 1 cams! the fuel mods that my guy told me about was a fuel pressure regulator cause u can tune your top end more and fuel rail wouldnt hurt. I dyno'd at 175 with cams.My q/t mile time was 14.3 and a 60ft. of 1.7 with out slicks. Yeah u will be fine with stock injectors, dont touch them.

P.S. get a trottle body u will get some of the response back u were talking about that u lost, i had the same feeling.
