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.

Not what I was expecting

Reviewed By Daniel B (RIO RANCHO, NM) Reviewed for a 2013 Dodge Ram —6/21/2017 8:58 PM

I'll start by saying I was skeptical. First time using a tuner and I know it should help but never really thought it would be all that noticeable. I used the canned 87 octane tune as I use my vehicle for commute by it really did make a noticeable difference. Much more response with better economy, it's a double win for me. Can't imagine what a 93 custom tune would do for it! If your a first time buyer I would definitely recommend you try it out, you won't be sorry.
