I found the exact same thing with my top swapped car.

From talking to the guy he also said that on the low compression grand prixs generally they like 17* or 18*..... Its no surprise I have aarons car running 18*..... FYI reason he was running such bad numbers IMO was a combo of a very rich tune + a slipping blower belt (WAYYYY TOO BIG)..... These have been fixed and the ******* thing is silly. Still a tad rich though running 11afr

The reason I KNOW he was rich because a week later we did some logging and were pegging the wideband at rich.
