Not to my knowledge, no.



I've never experienced anything like that. Though I have DCT. Still that sounds really bizarre and I question why it would ever need to do that.
I gave it plenty of gas and came close to matching the rev, but I was a bit under throttle for sure. It might have been a good thing, because that close to redline and any more throttle might have screwed me.

As to the tach, I'm getting worried now about it varying quickly like that. Need 6MT guys to speak up to confirm, but I think that's normal. I think it only happens when you hit the rev limiter so that you can give the engine a second to compose itself before you beat it up some more. It rises back up to normal within seconds (1-4 seconds or so). I would think guys who track their car have seen this, but if not, then I better get my car in for service.
