Message at higher boost levels - namely the timing is far too advanced under high-load condition and it will cause it to detonate.

One could pull the timing back at the CAS to correct this one problem, however, it is going to mean elevated EGTs at low and midrange RPMs, poor fuel economy, and you wont pass emissions. The other problem is the fuel delivery. It is not recommended to turn up the boost on a Z that doesn't have the proper ECU program in it, unless you want to run race fuel all the time.
