It seems that there fuel system is just like a turbonetics kit, 2 extra injectors that come on when boost is happening. The thing you need to think about is why are you buying all that stuff to get running by tunerfest, and not run at least a somewhat bigger injector. Do you want to spend that money and possibly have issues? Stock injectors will probably make out about 170 ish if i had a guess, and that guess is based on stock fuel pumps going out at around 200.
