so many times I've heard people say "put a race tuner on my bike" or the like, kinda like the PC and Fuelpak, where an item is actually attached to the bike bike. SERT and TTS are the same in the respect that it's just a programming change, not a physical addition.
Yes there is a module you use but it is the device that allows your computer to "talk" to your bike, kinda like an interpretor. but once the tuning/download is done, the module comes off.
I have done 2 bikes with the TTS, 1-my 09 SERG, and 2- 07 FLHX. lot's of reading up front,but as long as you get the first part right, saving the original ECM settings, then you can't go wrong. , kinda like a failsafe.
while the pre made maps are good, you don't get the full advantage of the system unless you use the V-tune Process.
I have used the other systems in the past and all have their + -, but TTS makes so much more sense to me.
I going to be contacting Steve and Doc to see about becoming a TTS dealer here in Tennessee, where I can do the tune and save a copy of each ecm Calibration for safe keeping.
if anyone buys a system and wants someone to do it for them, PM me
