Does it take a bit of time for a new clutch and lightened flywheel to get settled in? I'm finding sometimes, particularly when I grab third on a low revs up shift from second, that it feels a bit "interesting" or "notchy" going in. I'd swear that if I leave my foot on the throttle just a fraction then everything slots in much nicer. Twice now when trying to move from reverse back to first the stick seemed to get stuck in neutral and I've had to let the clutch back out and in again to get it freed up. I thought it had gone after noticing it when I got the car back 2 weeks ago, but I've noticed it again yesterday and today.
Last thing I need is a gearbox going tits up, but it was perfectly fine before the new clutch went on. Oh and I felt this before the remap too, so doubt it's a power issue. Have only done about 400-500 miles with the new clutch and lightened flywheel also.
