This programmer works great and delivers several preset quick-tunes as well as custom tuning on specifics like shift points and shift torque and will also recalibrate speedometer to your different tire sizes. It has a performance tune, 87octane tune, tow/haul tune and fuel mileage saver tune. Check the SUPERCHIPS website for confirmation of compatibility. This model is for GM gas and Diesel engines and I've tuned my 2010 Silverado with 5.3l V8 and my 2011 GMC Sierra with 5.3l.
