So the belt was slipped off? And it was acting up b4 hand?
I myself am not blaming it on the tune,but i have been told(by urself) and others.esp on CLUBGP that not so much a fried PCM but a malifunctioning one can cause a bearing to spin as well as a messed up tune. Now if the PCM is faulty,it can still run fine but all it takes is one lil fuck up or wire in the hearness for the PCM itself or circut to heat up when the motors warm and KABOOM ! U know what i mean. I have see nit as well as heard about it b4. How was he running b4 hand? It sucks when u cannot figure out the problem,i know
