Get some logs and post them up. 10.0 AFR isnt motor ending, but that is a tad rich and can slowly harm motor components over time as unburnt gas ends up washing down cyl walls, which clears away oil and lets metal on metal abrasion occur slowly, scratching the walls . Even some reputable tuners wont go past 10.5 when tuning for a very rich mixture. The optimal range is around 11.1 for most Top mounts , even up to 11.4 with a FMIC because of how much cooler the charge is.

Listen to skatendestroy, he is an expert with tuning these 68HTA's.
