I'm looking to put a programmer/tuner on my 2010 Sierra Crew Cab. It's got the 5.3 V8 and it's 4WD. Trying increase my MPG, but also be able to change the tune for when my family and I go camping. Everywhere I look I'm getting mixed reviews on which are better. So, any and all advice is appreciated. And thank you in advance for the help!
Any issues related to FORScan application
