AJ, hope that you weren't parking in Parents' parking spaces at the weekend wink
I couldn't tell you which stage:
My car has a prototype head created by AutoDelta, it was the first one they did, but I can tell you that it is running oversize valves.
They also put in the fastest cams they supply.
The car is a lot smoother than it was before, so yes it's still very driveable, although it gets a little lumpy at idle.
The lightened clutch is a godsend, it's like I'm driving a 1.0 litre car, really aids the gear change.
Power has been increased by at least 35bhp and the torque curve is now a flat line from about 2500 - 7600 rpm.
