== Does not matter who 'tuned' it ... If it was programmed 8+ years ago.. that is an eternity i n the computing world. The program at this point needs to be updated badly, as well as checked at this ensure it is not harmful to the engine. Copy the program from the ecm and e-mail it to me for a proper review of what someone did in there.. and as well to ensure there are no fault codes being blocked that can reveal your current issues.

surging like that at idle is either turbo or fuel pressure issues ... or a combination of them.

So .. will it pass a fuel rail leak test?. What is the leak rate?.

also... you need to check the commanded vs. measured turbo positions in the ecm to see if they match. If they do not, then there is problems with the actuator being able to position itself correctly.

Commanded and measured do match, always at 4 never different. If you watch closely when you cycle key on off they do "flash to a change" but is very fast and undiscernible at best.
I performed a "install Calibration on a second back-up used actuator and it passed if you will correctly with no issues.
Yesterday morning it would not start, and was short on fuel pressure.(under 8000 cranking).
I will get more Data today hopefully, we are in the middle of Calving season and below zero night temps NO SLEEP but will get back on task. Thank You.
