I think as long as you are not red lining constantly you will be fine
I thought the game was to get the needle to bounce off the red line!! ..... no? 
Most annoying thing about DSG, Even in manual mode it wont let you do this, just upshifts
I don't see how that is annoying, bouncing off the redline doesn't do anything part from push stress in the engine, the power has tailed off by then and you'll be going slower so what's the point?
