It's a long shot, but check your exhaust studs. I had decel popping and sluggishness show up out of nowhere last week on the way to work. Checked the bike over when I got to work and found a stud sheared. Just dropped it off a couple hours ago to get fixed. Good luck.

When was the last time you cleaned the filter?

Just replaced the fuel filter and air filter a month ago. Not sure which one you are referring to.

Air filter, thought you had a heavy breather. Dirty air filter can make it run a little rich

There are 3 buttons for fuel adjustment on the front of PC3 USB. The PC5 is the one with no external buttons.

If you had no decel pop for a week the problem is not in the PC. Check for intake leaks. If the problem is with the PC take the "0" percent throttle setting from 1500-5000 setting and set it to -10. See what happens. No pop. PM me if it does.
