Finally got a decent day to take my ECUnleashed flashed YST for a ride. It was all on road, so these are just my observations for that; I went maybe 50 miles. I have the stock exhaust system, no mods.
First up, Tour Mode: They definitely changed Tour mode, unlike what the sales rep claimed. I found Tour mode much easier to ride around town. At lower revs and in lower gears, it is way better. Much smoother throttle response, no snatchy throttle anymore. Once you get the revs up in Tour mode, there is more power than before, or better response, or it just wakes up more than before. Not sure how to describe it, but overall, I like it. Still cool, calm, and collected at the lower RPM's and gears, but with more get up and go when you get the revs up. Engine braking is diminished, but not gone.
Sport Mode: OK, now it is starting to remind me of my FJR in Sport mode! Once again, smooth throttle response. But no waiting for the revs to get up for the motor to come alive, it's on right now. Engine braking is similar to Tour mode.
In both modes I noticed that the engine lugged better at lower RPM's, didn't have to downshift as much. It also pulled away from stop lights better. Engine starts quicker, revs quicker, runs smoother. I like it. I was thinking of getting the Arrow headers and a can, but now maybe not.
