It can also depend on what you have installed. My Rushs lip-ons are notorious for decel popping. As much as the dealer would like me to spend $400 to re-dyno, he said this is normal for Rush. If I short-shift a bit, I can avoid it... but why do that?

I have a PCIII USB, and have used it so far with three different mufflers.
My personal experiences taught me to add fuel in the "throttle / RPM range" that pops.
For instance:
I have a tach on my bike, and it showed that I would get a decel pop when I let go of the throttle, and the RPM were at 3000 RPMs. That tells me that I need to add some fuel at 0% throttle, in the 3000 rpm cell on the map. I would start by adding 5% in that cell, and do a few revs with the bike hooked up to my PC. I would continue until the pops would go away.
Don't get me wrong, this is not a substitute for a dyno, but does work for the decel popping that drives people crazy.

I have minor decel popping and I love it. 
Mine happens when I gear down decelerating. I have Stage 1 and the older SE slip-ons. Sooner or later I'm probably getting a 2-1 Thunderheader and then even louder music from the rear.

I put the Samson Fishtail drags on my 09 this week and put the baffles in them due to the fuel injection and all that..........I cant buy a pop.
Without the baffles, you have to buy super tuners and filter and dyno and they will still blue and turn beet red. Seen too many fuel injected bikes try to copy my old carburated samson fishtail sound.
I had the same samsons on my 03 carburated and they were NASTEEEE !! No baffles of course. Loved them...nobody would ride behind me.....The backfire could be heard from six counties !!!
