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

Bully Dog GT in a 1999 Chevy Silverado 5.3

Reviewed By Tony P (ROLLING PRAIRIE, IN) Reviewed for a 1999 Chevy Silverado —8/3/2014 7:31 PM

I am very impressed with the programmer. It made a impressive difference in power. I never used to spin 35s unless it was wet out. Shifts are solid now and mpg is a little better. It is somewhat noticeable, but definitely worth it. It is somewhat confusing during installation. Youtube helped with my confusion but its in and working. The screen is also kind of smaller than i expected. Smaller than a iPhone 4 screen.

With the discounts that AutoAnything offer made this a smoking deal! I am very satisfied with this programmer. It really "woke" up my truck.
