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


Bully Bully for Bully Dog - I Like This!

Reviewed By Thomas F (HUNTSVILLE, AL) Reviewed for a 2004 GMC Yukon XL —11/27/2013 3:51 PM

I chose BDog because it would also display tranny temp. I've been towing a 24', 4900 lb RV with a Yukon. Upgraded to a 34', 7400 lb RV. Pulling the old RV, I got 10.3ish MPG (w/o BDog). I installed the "tow" program & towed the newer RV & added 2 kayaks on top of the GMC and got 11.2ish MPG. On the hwy not towing, my MPG went from 17.9ish to 20.1ish MPG (using the GMC trip comp). On my GMC, you have to remove fuses to program the BDog but just install "tow" & leave it, no reason to change.

Bought for more MPG's!!

Reviewed By Daniel H (PEORIA, AZ) Reviewed for a 2008 Ford F-150 —6/19/2015 1:45 PM

Bought mainly for the gas savings, and let me tell you, I am FAR from disappointed! Average now is between 17.5 to 19.8 mpg's with 275/75/17 a/t, k&n filter and exhaust work. The added power is just a fun plus too!!
