Re: Pcm

The PCM must be programmed to the specific vehicle, including VIN, transmission type, rear axle ratio, tire diameter, etc..

Re: Pcm

A GM dealer with a Tech-2 can do it, assuming you want a factory calibrated tune for a stock engine. Or a “mail order” tuner, like pcmforless in Stow, Ohio.
