DougL did some datalogging a while back and this "recipe" that was created and has worked very well for me and some others in reducing the afterfiring.

Pig9r--If it's not caused by a lean condition, what does cause it? When we had carbureted engines, there was an accelerator pump to add that initial bit of extra fuel when you suddenly gassed it. What it feels like now is that it needs some extra fuel when I suddenly "blip" the throttle. That's why I was suspecting some leanness. Also, I wanted to mention that not all, but most of the decel popping went away with the new tune. I'm really OK with that part of the mapping. To fix my problem, I'm just wondering where to increase fuel if, in fact, that would help at all. One of those backfires through the intake caused my engine to die, so I really do want to work on this aspect. Thanks-Ken B.
