Installed a Fullsac Stainless DX header and 1.75" baffles, Sunday. Very easy install and getting the pipes off allowed me to install more of my polished chrome bolts. I don't have a laptop but my Aunt was kind enough to come by with hers to assist. After installing the TTS software and updating, we ran out of time Sunday and resumed today.
Previously, I had an intermittent issue with the bike turning off while the on /off switch was on unless I started it right away. Also, the red alarm light would come on after riding a few miles. Dealer thought it was related to the Kuryakyn LED Turn Signals I installed. Did not seem to be a serious problem until we began the TTS reprogramming. Today, we could not keep the bike on to complete the reprogramming. Calls to Fullsac and TTS did not help though both tried their best, thinking my battery might be low. Put the bike on a charger but it did not help. Then, we could not get the bike to start at all! Finally had the bike towed to the dealer and got there at 6:00. One of the techs dug in and reflashed first my ECM and then BCM, trying to diagnose the issue. Finally and fortuitously, he got the bike to stay on by pushing extra hard on the on / off switch which turned out to be defective and the root of the problem!
I put the bike back together while the tech replaced the switch. My Aunt brought her laptop to the dealership in the evening traffic and we completed the reprogramming by about 8:30 p.m. That made for a very long day! I can't say there is a lot more power but the bike certainly runs smoother and is more responsive with the Stage 1. I'm blue and tired but thankful and happy!
