honestly i would need to know/see/compare the final set up, and how bolt on it is, and see the cost/hp..

like if its a $2000 kit making 50 hp, i would probably highly consider it.
if the stage 2 is another $400 and gains 15? hp, probably still..
if it starts getting more expensive.. i would start pricing a cobalt ss swap..


2 big things though is emissions and how reliable it is.. like i dont trust the "5th" injector stuff, or sticking resistors in things to trick the computer...
