Bully Dog Triple Dog GT 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.

Edge Evolution CTS2 Programmer Reviews


Saved my truck!

Reviewed By James R (CROSSVILLE, TN) Reviewed for a 2008 Ford F-150 —6/12/2016 9:46 AM

I have a '08 F150 4.6L and I had just bought a 27' RV and it was putting a huge strain on my truck in the hills and mountains of Tennessee. I purchased CTS2 along with volant cold air intake before a vacation to Florida and WHAT A DIFFERENCE!!! The tune for towing saved my truck from killing itself to pull the RV. Rpms never went above 3800 even up the steep hills...if your towing anything this chip makes a world of difference I would recommend for sure along with autoAnything...great service!
