I have a tuned PCM for my 1997 Z71 sitting in my garage. The truck is currently for sale, and I was just wondering if it is worth attempting to sell the tuned PCM seperate, is there any market for these? Maybe sell it for $50 or so? If not I will just include it with the truck when it sells, there is a potential buyer coming tonight so I need a quick answer. It is tuned for firmer shifts, 33s, dual octane (89/91), higher rev limiter, and no governor. Thanks guys.
