Yep, found the sweet spot (for me) on my 2008 FLSTC: This was after reinstalling a Cobra Fi2000r. I had not learned of the TFI before I bought that. For some reason, I had pulled it off after installing the info below and had the bike dyno tuned at the dealer with a SEST...Let's just say the result of that was underwhelming performance. So, today, I reinstalled the Cobra with updated settings for the stage 1 equivalent download and all I can say is the bike pulls and pulls and is big fun to ride again! I will put the 255 cams I was going to install on the shelf and keep them for my 2013 Street Glide with detachable tour pack! Bike as now equipped: Cobra fi2000R tuner Cobra Speedster longs Stage 1 air cleaner Detachable soft tour pack Luggage rack/passenger backrest Kuryakyn passenger running boards Kuryakyn Highway bar/crash guard with extendable foot rests. Will post pics after I hit it with Pledge. THIS SITE ROCKS!
