Just returned from testing the new mapping with and without G2 Throttle tamer. The mapping without the G2 Throttle tamer is really smooth in all modes. I tried everything to get a snatch out of the bike and failed. I rode over poor road surface, old tarmac, rough ground going around bends purposefully trying to ride on the worst road surface i could find....and there was a lot of it on our crap UK roads! The bike never surged forward or stuttered but remained smooth regardless of what was thrown at it-in all modes....I was really harsh on the A mode and had a couple of surges rather than snatches in 3rd gear but only because i was heavy on the throttle and the bike was responding as it should with its aggressive power. I then switched back to my G2 Throttle tamer and couldn't tell any difference in STD and B mode. It felt identical to the stock throttle tube...smooth, predicable and progressive...(and fast!) The throttle tamer became slightly evident when i was again being rough with the bike in A mode in 3rd gear and the surge forward was hardly noticable...as you would expect, after all, that is the G2 Throttle tamers job....but bear in mind that i was riding like a madman and looking for trouble. If i snapped the throttle back in any mode than it would wheelie...which is what i wanted it to do-no loss of power!
I would recommend that if you have the Throttle tamer fitted, then keep it on, it will make your A mode just that touch smoother, the B and STD mode you wont notice any difference.
If you haven't had the new mapping done-then get it done....it's a different bike and you will not be disappointed...it is smooth in all modes regardless of how you ride. No loss of power at all-but more fun because the power and stability of the bike is more predictable and settled-you will feel invincible.....and make you 18 years old all over again....Enjoy! (The G2 Tamer will be staying on the bike but could quite happily manage without it!)
