Plug off the air going to the exhaust ports via PAIR valve. Go to the bottom right side of the air box and find the T junction with the apox 1/2" black hose which leads to the front and back cylinder and PAIR valve. You need to plug this connection. So pull it off at the T and plug it with a 3/8" rubber plug that you can find at any auto parts or hardware store. It works perfectly and no more popping at all.
No other mapping or re-tuning is needed of you stick with a stock Suzuki air filter.
