Does anybody know about changing programmer from one truck to another
would like to use bullydog out of buddys truck he traded in it is a bullydog
power pup ,My truck is 06 lbz so was his?????

It should work, we have two Lmm's and have used the powerpup in both-just have to program back to stock on one before using in other. Make sure he took the tune out:)

It will work, just make sure he goes back to the main menu to return it to stock and not just put it in the stock tune. This is a very common mistake.
