Anybody running an Edge Evolution on their Duramax and experiencing "engine power reduced "message on slight inclines or small hills (when pulling 5th wheel--ours is 3600 Big Horn)? Edge is set to towing mode and truck power reduces dramatically down to 5 mph. This didn't happen until I updated the software in May (worked fine til then). Edge thinks it's the DPT filter clogging; I think it's the software update. I'm having it reprogrammed back to orginal version of the software. Truck doesn't do this in stock mode.
