So almost two years ago I bought a 2002 Road Glide. Previous owner did a 95" big bore kit, 6 speed Baker tranny, added oil cooler and also installed Screaming Eagle Racing Tuner kit. The bike also has Screaming Eagle mufflers on it. Basically he was going to make a fast Road Glide and even used Brad Penn racing oil which my understanding, not California friendly.
Fast forward to last month, I took the SE mufflers off and installed a DNA slip-ons, obviously for the "sound" reason. Afterwards, I noticed a different idling characteristics, especially on stops or traffic lights (low RPM). Also there were some deceleration popping happens.
Now, I'm not technically inclined but I'm wondering since the bike has a SERT, would that means I have to remap or retune the bike? I called local MoCo and they said ride it for a little bit and see if that will reduce the "problems". I also asked an Indy guy and he said if I just putting slip-ons, there is supposed to be no need to do a remap/retuning.
By the way, I called few local MoCos in the area, apparently they don't do SERT anymore.
Soubds like you're getting some reversion from the less baffled pipe. Nothing major. You could try some Thinder Torque inserts for about $20 from DK Customs too.
As for tuning...
Yeah it's sticky here in SoCal these days regarding tuners. Most have moved out of state and dealers can't legally do any tuning besides EPA friendly flashes to your ECM. The SERT was replaced by the SEST, and now the Street Tuner (basically EPA restricted). You can look around for an indy to tune it, go out of state, or swap to something more user friendly to tune yourself such as a Powervision, TTS Mastertune, Power Commander, etc. Not sure what compatibility you might run into with your older ECM. Fuel Moto might be able to recommend something.
The PO went to a lot of trouble, it seems, to ensure his modified bike was running just right. Now you've changed something and upset things! Find yourself a shop who will retune it for you - or put up with it. I don't see the point of changing to a different tuning device, the one you have is fine.
As for the SERT, the MoCo has been sailing close to the wind for many years now, making EPA compliant bikes, but making a ton of money out of selling products expressly designed to undo those EPA settings. We should not be surprised that they have finally been rapped across the knuckles! Which is why dealers are less likely to retune a modified bike to non-EPA settings.

Thank you Thingfish. I will look into. Do you think it will eliminate my popping thou?

Thanks Mr. Brown. Looks like (hopefully) I just need to tune it.
Yes Indo, tuning will eliminate your popping the best way as GRBrown mentioned, but the Thunder Torque Inserts from DK Custom might work. For $20 it could be worth a try.

My only reservation with it is that I have to take the baffle out. At least according to the instruction videos I saw. I wish I know all about this before getting the DNA slip-ons. I could've done it on the Screaming Eagles mufflers previously on the bike.
A local Indy guy will do the remap for $300.00 including the "thing" he needs to purchase online (from out state) and supposedly the person that buys the "thing" must have a dealer licensing.
