Deceleration popping after smog block off

Installed block off plates and removed AIS system and I seem to be getting the same if not a little more popping coming from the exhaust during deceleration. Any tips on this? Also, installed PCV, is dyno jet's fuel maps, on their website, the only maps I can download to the PCV? Thanks.

The popping is normal after removing the AIS. Enjoy it.
Only Dynojet maps on the PCV.

Re: Deceleration popping after smog block off

it can be eliminated with adding fuel to the map when the throttle is closed. it pops because the stock mapping is designed to go lean when the throttle is closed for emissions. on my R1 my flash software can turn this off in the ecu and it eliminated the popping 100%. however I do like the sound of it. I may turn it back on.
