Bully Dog GT Platinum Tuner (49-State Legal) Reviews


Very glad I got it!

Reviewed By Christopher B (WEST HAVEN, UT) Reviewed for a 2001 Chevy Tahoe —6/2/2016 3:29 PM

Hardest part of installation is running wires and stuff. Bought this tuner after reading reviews on others.Bully Tech support is very helpful! Installed performance tune and drove to work for a week. MPG went from 17 to 20! Installed tow tune and pulled my 5800 lb travel trailer with full water tank.Tow MPG went from 9 to 13 and went faster up the hills with less downshifting! The driving coach takes a few drives to get used to but not a biggie!

Made a noticeable difference performance wise on my Ram 1500 hemi. Big increase in power in the lower to mid RPM range. Still a new product so waiting some more features to be released for my application.
