TruXP Xtune Performance Tuner Reviews


works great

Reviewed By jim f (PHILPOT, KY) Reviewed for a 2010 GMC Sierra —1/27/2016 9:54 AM

Purchased this to get rid of AFM. It was on sale and about the same price as the thing that just plugs into the port to just get rid of AFM. The Xtune can disable AFM along with most features of more expensive tuners. The mileage tune was installed and couldn't be happier with the results. I would recommend this tuner.

Hypertech Max Energy Programmer

Reviewed By Jack S (Kearney, MO) Reviewed for a 2011 GMC Sierra —1/21/2016 7:16 PM

Installed in 2011 GMC 1500. Easy installation, truck runs much better. I really like the fact that I was able to disable the FMA.
