With my stock tune (well stock tune with no codes and better fan temps) I am having an issue in Drive. I drive in OD all the time and my AFR gauge reads between 12-15 depending on if I'm going WOT or cruising. But when in Drive only when I hit the gas and let off, the gauge reads 22.4 and I have to hit the gas pedal to bring it back down. Since this only happens in Drive I believe it is not a problem with my gauge (but I could be wrong). What could be causing this? Could there be a problem with the tune, even though it's basically stock? Is anyone else having this problem?
If anyone wants my tune posted let me know how to post it
Until I know more about this I'm going to do the easy fix and continue to drive in OD
