Rough idle, bad mpg

[FL_Cracker]

I just got new stage 2 injectors, turbo, and srp1 HPOP installed in my truck. When it first starts warm or cold it usually romps pretty hard and I have to give it gas to even out. Highway driving seems okay with a little bit of stumble around 1600rpm but runs really rough once I get off highway. Sometimes it will smooth out after a few min but sometimes it won't, sounds like its got a big cam in it or something. I think the mechanic did the ipr. I unplugged the icp idle jumped foor a second and check engine light cam on but seemed to run about the same

Ideas?

Most likely injector harnesses. I'd start there.

Replaced the harness when all the work was done. The truck just got scanned. Mechanic said the high pressure oil readings were all over the place and read really low when the truck did the romping thing. ICP? The irp is new. Ideas?

unplug the icp sensor and see it runs smooth,if so replace it,or mabey when the injectors were installed might have torn an oring

Replaced the icp today. Runs much better but not totally right. Oil on the old icp is dark and thin but i just had a oil change. Is this normal?
