If you did not remove the PAIR valve system and install the block off plates it likely the source of the popping on decel.
The easy fix is to lift the fuel tank and find the hose from the pair valve that plugs into the bottom of the air box. It will be located at the right rear corner on the bottom of the air box. Unplug that hose and put something in the end that seals it off. I have heard of some using a screw large enough to fit into the end of the hose, or even a marble of the right size. You may also want to find something to cap off the location in the bottom of the airbox where the hose was connected.
If this stops the popping you can leave it as is and it will do no harm.
Personally I prefer removal of the PAIR and installation block off plates, which is a bit of a pain in the butt to do. If you have Ivans most recent reflash you should not get a warning light from removing the PAIR. Otherwise you will need to do a jumper wire in the PAIR connector once removed.
