Will adding air stop popping?
Stock 2010 FXDC w/XIED's ran fine with stock mufflers. Added some Rush slip on's (Slash Cut w/1.75 baffles) and had a bunch of popping, so I removed the XIED's. Popping was greatly reduced, but not eliminated. I was thinking that adding a Stage 1 AC might allow me to reconnect the XIED's and eliminate the popping. My logic being that more air will allow the unburned fuel, that is presently being dumped into the exhaust system, will ignite in the cylinders. I know that a module with the correct map will accomplish what I need, but my pool and boat are both eating up cash also.
What do you guys think?

Don't have XIEd's but have a complete stage 1 with SE freeflow filter, V&H Pro Pipe Chrome with quiet baffle and a V&H FuelPak, and get some popping on decel. Have checked the torque several times and everything is tight. I think this just may be normal. I read a lenghtly article on this a few years ago and I think it summed by saying it is a non issue.

Was the popping reduced at all? I can live with it the way it is now for awhile, but I'm just thinking the AC would have some effect until I'm ready to get a proper tune.

First 2 things to check for decel popping are exhaust nuts, an exhaust leak will cause it, and throttle behavior, only partially rolling off the throttle will also cause decel popping, close the throttle all the way when you shift or slow down, and see if you still have it or if it decreases.

You may have leaned your Air/Fuel ratio to much. This will cause popping as well. Check your plugs. Change your plugs to the standard HD plug, not the SE plugs. Run your bike for a while. Then check the color. They should be a light to dark tan. If they white, you're running lean. My bike did this when I changed my mufflers.
Have you done a Stage One yet? The dealer can remap your engine. Not cheap though.
But, to confuse you more, with just a muffler change your O2 sensors should be able to adjust.
If your too lean you can cause a piston to burn.

There are no exhaust leaks, and closed throttle makes no difference. It pops less with the factory AFR setting. With the XIED"s the richer AFR made it pop more. Exhaust in the pipes is black as it should be. I'm just going to upgrade the AC and see what happens, and if that doesn't work, I'll decide on a module.
Even with a little bit of decel popping, these Rush slip ons sound bad a$$.

My signature shows what I run on my F-Bob. I get some slight decel popping every now and then, sometimes on a cold start, sometimes on a warm start. Changed exh gaskets and muff clamps, torqued and re-torqued, intermittent popping still occurs. Spark plugs are off-white/tanish. I just live with it.
