I purchased this programmer along with a K&N FIPK Air Intake and my truck is like a rocket! Huge difference in power. I'm trying to lay off the gas so I can check my mileage, but havent't been able to yet!!!

This is my second superchips tuner I have purchased, one for a 2009 Sierra and this one for my 2013 Sierra. Combine this tuner with a good cat back exhaust and cold air intake setup and you can tune your truck to run the way you want. Very happy with the ease of use when connected and making changes. No going to the dealer when installing larger tires to get the speedometer reset.
