Power down?

Wayne, I have recently purchased 2001 e46 m3 and I do not think it is producing enough power compaired to another one I drove a year ago. The Vanos unit was replaced at the dealer some time ago, do you think I should check the cam timing?? incase they stuffed up? or any other ideas??? apart from that all service items seem to be up to date.

It's impossible to tell and compare to a car you drove a year ago. If you think that something is amiss with the car, then pull the codes and see if there are any problems. If you think the cam timing is off, then you can plug it into the computer and read it and check it against the spec.
