Right now I have full exhaust including midpipe, 255 fuel pump, intakes, and am currently running 12 psi on the M2 stage III. Could I plug up the power fc and run the same amount of boost? Or do I have to tune in some sort of way? If so, could you tell me what to adjust?

 

you would have to tune. but if tuning from a stock map with your mods, it will take less then an hour of dyno time. If you plan to mod the car more in the future you will need a good stand alone like the power fc. Otherwise you risk blowing your motor.
