please help!!! having a major problem with my 06 mega cab. truck runs fine till it gets up to operating temp then it just loses all power. i even have a hard time doing 60mph without pulling. egts start running hot and will show a 100% engin load but can't accelerate. i've tried cp3 upgrade but that seems to be working fine, tried restictor valve on common rail but that didnt help, had computer flashed, still not better. had a guy that works for a dodge dealership as a diesel mechanic look at it on the side and he cant seem to figure it out either. any suggestions would be great. thanks
