Yep, did the same thing: I installed the 2" Full Sac baffles in stock 09 SERG pipes, then removed obstruction in head pipe, and installed Full Sac map with MasterTune. Had some issues loading software on laptop, then had issues downloading updates. I was pissed!!! Started emailing and calling Full Sac during the weekend. Once all of that was behind me it was easy to program the ECM. Only rode it 1 mile, started raining again, (North Atlanta) but could tell a big difference. It starts better, sounds better, and throttle response off of idle is quick and crisp. We're Headed to the Thunder Beach Fall rally in Panama City Florida day after tomorrow. I'll know more about the performance i.e. fuel mileage, cylinder temperature, overall power, smoothness, and accurate speedometer reading, after riding it down there. I'm sure it'll be all the great things I've already read about on this forum, and on the Full Sac website. But one thing is for sure, Steve and David at Full Sac are customer service oriented, very responsive to email and phone calls. It was the weekend and I still heard back from Steve, several times!
