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.

Works well with my 2011 Silverado. Very easy to install and I went from 14mpg to 16mpg in town and it gave it noticeable more power.
