TruXP Xtune Performance Tuner Reviews


Does what It says

Reviewed By Judd B (WEST LAFAYETTE, OH) Reviewed for a 2007 Chevy Tahoe —6/20/2016 12:45 PM

Was looking to firm up my transmission shift points and disable the Active fuel Management system, This unit allows that to happen. I wish the instructions were a bit more specific as to what every setting can and will do, but I guess I'll figure it all out eventually. The performance tune is a noticeable difference from your stock tune but again I wish I had more details about the tune itself.
