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.

Bully Dog BDX Tuner Reviews


IT WORKS!!!

Reviewed By Chad H (Bivins, TX) Reviewed for a 2012 Toyota Tundra —7/25/2017 8:36 PM

Very easy to use. Just follow the directions. Received the BullyDog BDX one evening and had my truck programmed the same evening. There are several settings. I only chose a couple to begin with, but noticed the extra power immediately. Ibis will it set in economy right now, but I haven't noticed a tremendous increase in mpg yet. I mainly got it for towing my camper which is 37' bumper pull and weighs 8800 pounds in the dry. So far, I am very pleased with the BDX.
