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

Buy it.

Reviewed By Michael P (Chehalis, WA) Reviewed for a 2006 GMC Sierra —9/23/2016 6:58 AM

After a month of solid research i decided to go with Bully Dog. Very easy install, excellent graphics, produces the best information from your vehicle. The Tow tune turned my sluggish truck into a sports car like feel to the drivetrain, great shifting, and perfect use of the 5.3 power band. If you have the chevy trucks made between 2000 and 2007 (classic) you should have this tuner.

thist is the 3rd Hypertech Programmer I have had and with no exception this is the best in performance fuel mileage. I bought for my 2006 GMC duramax 4X4. Has K&N filter, 4" exaust and oversized tires. The programer does everthing it said it will do - more fuel mileage, power and corrected my speedo to macth my tire size. Thanks Hypertech.
