TruXP Xtune Performance Tuner Reviews


Excellent upgrade

Reviewed By TERRY P (FORT WORTH, TX) Reviewed for a 2009 Pontiac G8 —4/5/2016 9:36 AM

My first upgrade to my 2009 Pontiac G8. Great bang for the buck. Upgraded the programming online as instructed before installation. Noticeable increase in power with slight increase in fuel mileage. Still fine tuning the setup on the car to get the best combo of performance and mileage. Why spend more for the same improvement with another tuner?
