Noticeable difference in power. Easy installation. Transition through the screens and adjusting minor settings can take some patience.

I installed the bully dog-6 position chip in a 2001 excursion 4x4. I'm getting about 4 mpg more under normal driving conditions. 16 city and 21 highway. The truck will get up and go now.

Noticeable increase in HP and firmer shifting at higher RPMs.
Lost MPG in city & HWY which was disappointing.
