Had software update done on my 15gsa gsap a couple of weeks ago, much much better, especially the 2-3 which before was violent. Also wiped away the high pressure and fully closed throttle to come down the box.
Don't get me wrong you still have to learn and adapt to using it, but where before I would think twice about adding to the buy list on a replacement bike, as it has improved with updates and as I get better at knowing what it likes, it's now probably up there with a top box on the items I would want if ordering a new bike.
