I'm assuming you have a M54 in your Z4 and not the N52 based on the fact your Z4 is a 2005. In that case I would look at two additional things. 1) Underdrive pulleys. You can buy these from Turner Motorsport and I think UUC or Rogue Engineering might have them as well. Basically the pulleys under drive your accessories like water pump, steering pump, and alternator (if you choose to). The engine will rev more freely and you will see a boost in performance towards the upper end. Factory pulleys tend to suck the life out of the engine. 2) Software. There should be plenty of stuff available for the M54 engine. Dinan, Conforti, and Active Autowerke are popular options out there and in general the tunes optimize your car to run on 91 or 93 (if available). In combination with underdrive pulleys you can see a pretty decent jump.
