Problems After Exhaust Install
So, I installed a new (to me) exhaust on my bike a couple weeks ago. Since then, I have started having problems with the bike coughing, sputtering and barely moving when I give it throttle. When I first start out on the bike, it seems to run fine, but, as soon as it gets warmed up, I start having problems that start with a little stumble and then gets progressively worse to where it seems like it's just going to die.
My current set up is:
2004 FLHRSI
TC88
SE Air Cleaner
Stage I Flash
RB Racing LSR 2into1
PCIIIusb
My local indy shop is telling me I need a tune because of the new exhaust. I have tried four different maps with pretty much the same results. The last one even came from Dynojet's tech guys. I find it hard to believe that the tune is making it run as bad as it is. Regardless, I am taking it in to have it dyno-tuned this week, which I was kinda hoping to save for later when I changed cams and such.
So far, I have checked fuel injector wires, exhaust leaks and have tried to find any pin hole leaks in the fuel lines. Any thoughts on what this could be and what else to check before I take it in?
Thanks!

I actually did. Took it apart, checked the throttle body, cleaned the filter and re-oiled.

I had the same bike with pretty much the same setup (only true duals). Take the PC out of the equation and see how it runs(short trip should not hurt). I always use dielectric grease on all connections, FWIW. Put your old mufflers back on and see if the problem goes away. Good luck, I sold the bike ('04 RK Custom) to my son, and it's still runs like a champ.

The exhaust is NOT causing the problem unless as frontiercat mentioned there is something got inside that shouldn't be there during packing and shipping. The prior tune isn't the problem. It is something you touched during removal of previous exhaust or install of new exhaust or anything(if any) you added at the same time. Go over your steps carefully, you'll figure it out.
