350bhp and 700nm torque (525ftlb?).
Throttle is more responsive and low down has bags of go, no real lag - certainly no more than previously. Definitely recommended. Haven't had a chance to really drive it but a quick blast and then the motorway home showed it was definitely quicker - flew up the slip road and foot down at crushing speeds it just goes.
Remap should have been 299, I got it for slightly less as I roped a colleague in for a deal on his 320d at the same time.
