Hehe cheers guys!
You have a 147 GTA now don't you James?

Haven't got a clue power wise I'm afraid, though it would be nice to be up there! There is a tophat shim dancing around somewhere as it is so loud from the top end. There is oil present and clearances are actually slightly smaller than standard. Peter has had a look and we'll be trying a few things to track down the cause.
You're right about the torque. Drove it for the first time to the petrol station yesterday and from just driving it normally I can already tell a massive difference in power from low revs, though Peter reckoned it felt tamer than it should. I'm happy though as the old 1.1 was just comically gutless in comparison until it reached around 4k.
Can't wait for these little problems to be ironed out.
