The truck throttle body is a different design than the car throttle body. The truck one is actually 87mm and the car is 90mm. Not a big difference, but my problem is that apparently the truck style doesn't always play well with the X-harness possibly due to the way it's built. I'm getting a P1516 code at WOT that I believe is due to the TB I have and I'm hoping the car style will fix that.

Other than a small adjustment to help idle learn quicker there really isn't any tuning that needs to be done for operation of the larger TB. The x-link takes care of it.
I have made some additional VE and idle airflow adjustments, but they are minor and are not tied to the P1516 code problem.
I think I'll double check that the TB I have isn't binding up in anyway. Maybe even take it apart and check it out before spending money on the car style.
