It might be because I am supercharged (Ess625) and have Akra exhaust. Exhaust note has changed due to different way the box shifts, it is very hard to described how it changed. It used to be more snappy, like click-click-click with abrupt changes in RPMs, now the noise is somewhat smeared, not as snappy. Not sure if others experienced the same. Dont take it that it is worst, it is just different. This is mostly noticeable when accelerating at say 40% in lower gears.
I know exactly what you're talking about. This actually bothers me quite a bit. Where it seemed the US program would cut throttle in between shifts, the gts software almost seems to slip into gear at partial throttle at higher rpms. Everything else is great, but this annoys as I preferred the sound of the US with my Akra
