Please read my post again. I think it is called
decel fuel cut-out DFCO it is differant than leaning your AFR like you was saying. Maybe
svede1212 can shed some light I think he tunes his own car. My car is tuned and it pops the same before the tune, I have the loud "snap popping" and high rpm raspyness when shifting that I don't like with the LMI's, I'm going with a custom Magnaflow setup soon.
