View Full Version : 2008 FLHTCU combo

07-26-2009, 04:53 PM
I have a 2008 FLHTCU, SE airfilter, stock motor, PC III USB EX tunner and Super Trapp Internal Disc Mufflers. The Power Commander does not have a map for these mufflers, how many discs should I use and what map would be close. I ride mostly 2 up and highway speeds some local riding. I am running M818-005 map right now.

12-14 rt muffler.
10-12 left muffler.

What about the map is that close enough to use with that disc combo? Thanks

Sorry, on the closed loop stuff, we don't remap anything here, the stock system adjust to run the same AFR as stock. So with testing we leave it alone.
I would assume that any map for free flowing preformance mufflers would be pretty close.
