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.

Reviewed By Stephen P (Albuquerque, NM) Reviewed for a 1999 Chevy Silverado —10/7/2011 8:49 PM

Installed in my G6 in 10 minutes, really easy just took my time to insure everything was correct. Improved shifting and throttle response. Looks like it improved MPG by close to 2 MPG in city driving. Bought Stage 2 in prep for other changes to come.
