Just curious, I don't see an upgraded computer in your list... Do you have one and just left it out or do you not really have one installed?

do you have a boost guage? If you do, maybe you can see what boost patterns your are getting and diagnose the problem from there.

One of the problems I have heard of top end RPM breakage was ignition related. Loose and/or dirty coil connectors could be causing the ignition spark to fluctuate at high RPM.

Possibly, you may be running too rich top end, also.

You better get the ECU properly mapped. The HKS isn't a solution bandaid, but it IS an east install.

As far as I know, XS http://www.xs-engineering.com/asp/index.asp doesn't make their own ECUs Is it a Power FC ECU that you bought from him?

If not, I'd personally just email him and ask him EXACTLY where he got that ECU from. It wouldbe your best bet. To be honest, I really don't know if a modified ECU from one vendor can be modified by another..

No, an ignition box like that will not cure a mixture that is too rich. You need to get your computer remapped for your car.
