Default ECM

Anyone out there with a 2007 - up 1200,or 883,run Cycle Shack slip on mufflers (MXL -130: 2 1/2" dia. not the 3" one); there must be some of you out there. What A/C are you using and did you just get a re flash, or some piggy back system add on? What worked? I'm considering "just a re flash" because I'm stopping mods at the A/C, and anyway I just found out (I have a 1200L) that I can't use a PC III because of fender clearance. Besides that Bill Gates is not my uncle.. Just have the slip ons right now (no ECM change yet) for the past 600 miles and theplugs look thesame as before I tookoff the stock mufflers. Everybody said it would be just loud, but it sure runs better (maybe the newer ECM auto tuned for the mufflers; heard the newer models do that). No dec el pops, nothing, but huge improvement from stock mufflers. Come on you guys Cylce Shack makes more than one muffler so I can't be the only one who bought them.[/align]
