I can get it occasionally on 91 octane (more often on winter gas), particularly around 4k Ti-VCT transition, under heavy load or right at shifting. It is light and momentary. Good gas and an occasional profile relearn that takes about 30 seconds with the tuner keeps it down.
line lock is fricking awesome. Not having to so the 3 legged race solo at the track on my stick mustang would help alot. It's not hard but, it's one more thing I need to get right for a successful pass. Tough noogies for me, anyway, I have a 2012.
