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


Great results EPA and performance!

Reviewed By Anthony L (Gig Harbor, WA) Reviewed for a 2000 GMC Yukon XL —10/7/2015 8:47 AM

So far I have put about a thousand miles on my 2000Yukon XL with the bullydog and fuel averages went from fifteen to eighteen combined with a noticeable difference in performance of throttle response. It seems like in time the Bullydog will pay for itself and make the truck more usable with both power and MPG increases. Auto anything did a great job on price and getting it here quickly once again. I would definatly recommend this product to anyone and suggest auto anything as he place to get it.

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.
