Well I wanted about 350rwkw. I was planning on full xforce exhaust 4" dump cat and twin 2.5" system but from what I have read its better to go a twin 3" system? Also wanted a rapid system intercooler, Intake plenum, 80 pound injectors, bigger fuel pump, wast gate and actuator with the custom tune. Not sure what I would get from that??? With 98 octane and a e85 tune. Just want to make sure the car is going to be up to scratch that's all.
