Range module worked awesome on my new 2015 Sierra Denali! Got rid of the jerky transmission and the constant changing between V8 and V4 mode. No more grinding noises when going from V4 to V8.

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.
