I personally just got the Bully Dog GT for Jeep and love this. It has lived up to all that was said it would do. That said I want to know what chips everyone else is running and what benefits you have seen. With this chip I have consistently got 3 mpg better driving around town and on the highway. Also this chip lets me have full locking diffs in my rubi in 2 Low and 4 high. It does a ton of stuff, l have really enjoyed this chip. What you run and what do you like or dislike about what it is.
