Just a quick question, I have a 04 LLY and I was looking at putting the Edge CTS evolution on it. Are these programmers universal on 01 through 2009 Duramax's? I know the Juice w/ Attitude wasn't, but i dont see any sites that have you specify which motor you have when ordering the Evolution. thanks for the help

They do work on all Duramax's 01-10.

thanks for the help

I have personally plugged my CTS Evolution into 01, 03, 04, and 06 trucks with zero issues. One of the best features about it IMO. Nice units.
