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.
