My buddy has a 01 Silverado with the 8.1 in it. He put a programmable chip on it to increase hp and gas mileage. He claims that it can be unprogramed and moved to another truck, and that your actually suppose to unprogram it before you have any work done on it from your dealer.

He is selling his truck and said he would give the chip to me if I wanted it. Will it work on a 02 Silverado with a 6.0

Any comments would help.

BTW if any is looking for a 4 door silverado with the 8.1 in ohio 4wd make a offer
