you probably are right, since its my work truck. I just has this annoying trait of not spooling out of a driveway (hill) with a load. A similar test is if i set the parking brake and floor it in drive, it revs to 1500 and smokes. I thought for sure my new turbo was going to let it spool up. I had check engine lights for a while all pertaining to vgt codes. I hoped it was stuck open, so it had trouble spinning up at low rpms. But it didnt change, at least no more cel.
