Hi, check for Codes in engine computer. If engine performance is reduced due to computer detecting fault turbo will not work properly. Maybe you have done it all ready, but I just wont to be sure.

hi, the only code was the one that always pops up when you install a program. (p0603)and there was a code when i first hooked up the EDGE it was a back pressure code. i disconceted the back pressure senser on the front of the motor and ran it. No change. i cleared all codes about a week ago and have taken the truck on a trip and there are no codes now.

Hi, back pressure sensor is treaded on top of a pipe that connects to exhaust, this pipe is plugged with carbon deposits and that is why no pressure there, best way to remove and replace.

Code P0603 is power loss to computer Keep alive memory, but if not coming back, it is just old code.

HERE read this, it is service bulletin from Ford if your injectors have not been serviced lately. this may be the problem.
