Despite it not being mentioned in the manual. I find NLS will still work in Sport mode but works BEST when you put it in Competition mode so that you don't introduce any bog.
If you are new to it and want to test it out. Try using it from 2nd to 3rd. It will be easier than 1st to 2nd. Just until you get the hang of it. Trust me it's the most unnatural feeling not lifting the throttle. Once you successfully get it down you'll love it and won't want to lift shift on WOT ever again.
When I first heard of it and tried it the first time. I didn't do something right and resulted in a pretty rough shift and I swore I would never use that again. However I'd find an on ramp or a stretch of open road and just give in to trying it again. About the 3rd or so try I finally got it and it is by far the absolute fastest way to shift this car. It almost sounds like the A8.. (I know not quite)..
Everytime he clutches you can hear and see the RPM's jumping to 6500.....
