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?

SCT X4 Power Flash Programmer (49-State Legal) Reviews


High Quality Product!

Reviewed By Ronald B (Frederick, CO) Reviewed for a 2001 Ford F-350 —5/1/2016 2:28 PM

This tuner works wonders for the 7.3 powerstroke. It pushes the motor to redline and when the pedal is mashed, keeps it just below it, so you're running like a banshee throughout the power band! All of SCT's research and development have paid off in this unit. Super product I would highly recommend.
