ECU flash tune VS powercommander /dyno tune diference

[Shifu]

Another question for you guru's.
With just a TRE, how much difference would be noticed?
I have a 2010 Gen 2, stock apart from R77 slipons.

Realistically, in your day to day riding you will probably not notice anything other than possibly the fuel consumption if the fifth gear map is different from sixth gear map (I can not remmember if this is the case). The TRE just messes with communication between the gear sensor and the ECU telling it that when you are in the sixth gear the bike is still in fifth. That is sort of a primitive way around the factory set speed restriction of 189 miles/h. The right way to do it is to read the program stored in ECU remove the restriction, adjust few other handy settings like fan start temperature etc and write it back to the ECU or "flush" it as it is also called.
