Bryce, I have an 03 Cummins w/ edge+ attitude. The only problem I've had has been that it throws codes whenever I get on it or am towing while getting on the freeway. It is nice having the built in gauges but it's also sort of bothersome having the check engine light on until it cycles three times. I had the edge without attitude before on this same truck and it never threw codes. My mechanic said not to worry about the check engine light for what it's worth.
