Can someone point me to the right PIDs/parameters for this ?

I'm not by my tuning laptop right now ... but I think there was a "decelerate enrichment" parameter, is there a corresponding "accelerate enrichment" ?

I've leaned out the OL commanded AFR for this car and it is starting to "POP" through the intake only when pushing on the accelerator real fast. If you ease into the throttle it seems okay.

The car is not actually lean (12.5:1 - 13.0:1 AFR recorded on the WBO2), just when first stabbing the throttle does it momentarily go lean and produce a "POP".

Hmmmm....mine does the same without the POP!
I'm wondering the same thing?
