tommys ss Posted February 5, 2004 Report Share Posted February 5, 2004 I have a Superchips Programmer part # 2715 that i had on my 2003 silverado SS . I had it installed for 2 months and since then did a supercharger upgrade . I bought for well over $300.00 and have it in box from superchips and ready to go to you . I need $200.00 for it and i'll pay the shipping . It was a big help in the trucks performance and I had recieved about 2-more miles to the gallon on fuel economy. Besides better shift points, Transmission preasure, tire size, any other modifications done, and check engine codes. Its an awesome unit if your lookin for some cheap fast performance. Thanks Tommy Link to comment Share on other sites More sharing options...
