Default 2010 "103" backfiring
I have done mods to my Limited with a PCV ( set-up by fuel moto and my local tuner with the same results ) Vance & Hines Power Duals, and Vance & Hines twin slash ovals.
The bike runs great, sounds great, but between gears at low rpms the bike backfires.
This is especially true when it's real hot out.
I have added 5% more fuel to the map at 2% throttle between 1500 - 3000 rpm with a slight improvement.
Is anyone else having this problem?

Mine does the same thing at times. I have SERT, stage 1, Rush pipes no cat and V&H monster ovals. Did you remove the cat with those pipes?

put 12's or even 15's in the 0 throttle position all the way down. It will stop. OR you have an exhaust leak.

Try unhooking the PCV. If it still does it look for an exhaust leak. My even try a Zero map first.

Then my money is on an exhaust leak somewhere.
