Intake Backfire??? 2011 Super Glide. Please Help.

UPDATED: Intake Backfire??? 2011 Super Glide. Please Help.
I have a 2011 Super Glide Custom that I have installed a V & H Big Shots staggered on as well as a Heavy Breathers and PC V. I installed the pipes first and it ran excellent. I installed the Heavy Breather and PC V and now when idling it develops as "hiccup" and sometimes (when cold) will die after a hiccup. It sounds like air coming backout through the intake (maybe an intake backfire??).
I had FuelMoto do a custom map and I still have the issue. I an new to all of this and am totally confused.
I am worried I will damage the engine if I continue allowing this to occur.
Any advice would be great. The stealership wants $92 an hour to diasnose and $400 to dyna and custom map it.
P.S. I installed everything myself and checked for an exhaust leak (Using smoke from a cigar) and could not find any exhause leaks.

Mine is doing the same thing sort of. Mine only coughs through the intake when it's cold. If it's hot outside or the bike is already warm it fires right up. Once it's running it's good to go, never had it stall after being started. Go to the powercommander website with your computer plugged into your bike and go to support and then remote desktop log in. A chat box will come up and once a tech shows up tell him what's up and he'll get on it. He got rid of my decel popping and the warm start coughs, but I haven't logged back on yet to take care of the cold start cough yet. If it didn't do it before the PCV it's the PCV. I'm sure the intake wouldn't make it do that. You can try pulling the PCV also and see how it starts. You aren't going to ruin anything.

The problem is occuring during the warm up, if I don't goose the throttle every now and again during warm up it will make that noise and usually die (not always). I have a few calls into Indy's that due dyno work and hopefully they will be cheaper than the $400-$500 the local Harley shop wants.
