HI,
I have an 08 A model. Since day one I have noticed at 2500 rpm to 2800 rpm the engine has a different sound and has a slight vibration to it. Under 2500 it is smooth and over 2800 smooth again. Yes around 2900 or 3000 rpm it is in turbo mode. Just curious if this is typical for this machine at that rpm range, also it does seem at that range from 2500 to 2800 it is like a flat spot.
Thanks,
Dave
