I have a 2003 Avlanche 1500 with the 5.3L motor. I have a nice amount of engine upgrades, and now it is time to do a computer. I have heard nothing but great things about your tuning programs. Please get back to me and let me know what information of mine you need to come up with a custom tune for my truck.
