allright, im running a pr3 on my b16, but the weird thing is i was throwing a code 4 right? but the thing is the cel would be on and my car would pull really hard and drive fine, but once after driving hard the car wouldnt rev past 3.5 and i know that deals with the code. but i put in my friends stock pr3 and it ran great. also ive tied numerous chips and it still doesnt work. but heres the weird part, i put my pr3 in my car, wont work, i put it in my friends car, works great. wtf?? so maybe its a electrtical short?? thats what im thinking. has anyone else ever dealt with this before? also right now im throwing no codes car runs great. but im on a ls ecu. so....can anyone help a brother out??
