If I don't time it just right, nice little fireball pops down the exhaust).
Are you saying you corrected your lean spots in that same A:F table, or elsewhere?

If you do like I did you won't have to backfire, I just drive and watch the correction factor and during live tuning while holding the pedal there while you feel it sputter add the fuel on the fuel comp table but don't go passed 100% leave it a little and I mean a little on the rich side maybe 95-97% and I don't backfire on decel from 7000k down to 800 idle.
