"Installed this programmer a couple weeks ago on my 2011 GMC Sierra 1500 4x4 crew cab. Have only used the performance quick tune and disabled speed limiter, but so far very impressed on how well it performs. Haven't calculated how much MPG gain yet... expected 3-4. Other additions include Airaid CAI and TBS(also purchased from this site) and Flowmaster turndowns. Definitely will buy again for future vehicles." —Kody D from Harvey, LA bought a Superchips Flashpaq Tuner for a 2011 GMC Sierra, 5.3L V8.
