Hi Im looking at buying the stage 2.2 performance kit from process west.its costs $2250.I was wondering how much would this increase power by on a stock bf xr6turbo? I will obviously look at a tune straight after..I would like to make around 300..would I need bigger injectors? Or any other mods to run this kit? Apparently an actuator is a good idea.....not too sure.and if I get injectors,which ones would I have to get? I have a full straight through exhaust..do I really need a high flow cat?couldnt imagine they would do much... Any help would be awesome..thanks ???
