3.0 doesn't necessarily mean a ZHP motor. They had standard 3.0 motors with 225hp and the ZHP motor with an Alpina cam in it making 235hp.

This is the first I’ve ever heard the zhp cam is in any way related to Alpina.
I feel like we’d be talking about that a lot here if it was.
Alpina was the OEM supplier. Nothing special about the cams other than they add 10 HP

Honestly his car feels closer to my friends 325. We're going to try spark plugs and air filter and go from there. Although I'm unsure what the next step is after that.Quote:

Your 330 with auto has a different diff with shorter gearing, so it should feel quicker.
Even with the different gearing they should feel the same. The auto has shorter gearing yes but also has a torque converter which robs a bit of power.Quote:

Vanos seals could be another item to fix but would be much less noticeable unless your pulling in 5th or 6th at low RPM's on the highway. For daily driving my bet is on a failing DISA valve.
Not sure on this, but could inadequate compression in the cylinders cause power loss? I know it is a common issue on these M54 motors.
