Very glad I got it!
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!

The system is awesome. It's easy to install and it delivers the horsepower. It's night and day on how it makes my 02 Tahoe 4x4 run. It saves on the gas and gives the vehicle world's more power. I'm very happy with the money I spent and the outcome of the preformance. You can't go wrong with this setup.
