I ran around on my 2010 for some time with a Stage II flash (SE255s) while pondering what product would work the best for me. Had experience with the SERT on my 2003 SE Road King. It ran ok and was done by a local dealer. Seemed at the time the local dealers loved SERT. But for me, its been more an issue of finding a trike dyno near me than what they tuned with. I ultimately went with TTS because I heard the owner was the man behind the SERT. It also had the V-Tune process, which at the time appealed to me for self-street tuning. I don't know anything about the others. But that's why we all come to a "forum" like HDF, so we can freely exchange ideas and thoughts. I'm just glad we can still do it here in relative peace and harmony...
