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

Bully dog rating

Reviewed By Tony M (Greeley, CO) Reviewed for a 2014 Dodge Ram —7/22/2015 6:31 AM

I was told by one of your employees that it would not void my warranty. I found out that it does void it also that the extra fuel it pumps into engine causes the exhaust to plug up. Wish I would have know this before buying it. Not sure I want to use it now.

totally worth it (gmc 2500 6.0)

Reviewed By Dex B (ALBION, IN) Reviewed for a 2004 GMC Sierra —7/12/2015 4:25 AM

I got the bully dog to try and increase my fuel mileage and give me a little more giddy up when I'm hooked to the trailer. Before the triple dog I was averaging 11 to 11.5 Mpg, maybe 8 with a trailer loaded down. Now I'm averaging 14 to 15 and 12ish with my trailer. Very good investment I'm glad I got that little bugger.
