Bad vibration when clutched in. [edit]

Somethings up. I've been running my clutch/flywheel combo for over a year now and this problem just came up.

Say I'm doing 70 in 6th, and I clutch in and bring the revs up. Above around 3k there is a HORRIBLE vibration that sounds like the muffler just fell of and the whole car rattles. It does it in 4th and 5th as well. It doesn't do it when the clutch is engaged, so I can pull to redline no problem. There is some shifting issues at WOT if I try to shift too fast from 1-2.

It does feel a little rougher at idle, especially at cold start up.

Is it possible my flywheel has come loose somehow? I loktighted the bolts, but the new flywheel is aluminum so maybe the heat changed the dimensions.
