Popping on Decel

Popping on Decel
Just installed Pipes and Air Cleaner with an Auto Tuner. Don’t have the money to have it put on the Dyno at this time. Plan on getting it done within a month or two.
Bike runs nice but getting a little popping on deceleration. Which way do I go with the tuner to eliminate the popping? More or less fuel on Decal to stop the popping?

Already checked and can't find any leaks on the exhaust.
The Auto tuner I have has a mode for decel. Plus or minus fuel adjustment. Just don't know which way to go. I will have it put on dyno later ( 2 months )
It's not a real bad pop and it's not all the time.
Will it hurt the bike if I ride it with the pop until I can get the dyno done

I had same problem. I've got PCIII and what I did was add fuel to the "O" column on left. I first started with adding 25, rode for a bit and popping was gone. By adding that high your also using more fuel, so I slowly started decreasing that number to find my "magic" number, Next I cut the number in half and added 12, rode for a bit and my poppong returned. Now I think I have 17 in that column and no popping and Bike runs well. Hope this helps

The Vance & Hines FuelPak instructions with the unit tell you, if you have popping, lean out the decel mode by decreasing one number at a time to see it it helps remove popping. They warn that you may get a stalling condition when coming to a stop if you take it down too much. I believe "trade-off" is the term they used. I'm running with a SE Heavy Breather and V&H BR 2-1 with the recommended FP settings. I get a pop or two occasionally but not bad. They state it's not harmful, just annoying.
