My son shipped his cars computer to get reprogramed and the carrier lost it. Anyone know the best place to purchase a replacement?
Beware where some are selling used units and you could be getting a PCM that came out of a 1999 truck and flashed software for your model year
New ones at GM are only around $150 and assures your getting new hardware for used ones could have weak hardware for injectors, knock sensors, ETC.
If your doing this yourself you need to do the PCM / BCM relearn and if gettting a lot of misfire the crank sensor relean to PCM
