Stock engine with a chip and headers. It was not a balanced and blueprinted engine, which I think is necessary to run at those RPM's under race conditions.

After my two engine issues, I decided to go down to 6500 and ran a full year and one half with no issues at all. Now that I have a blower, I will not be going above 6500 and really need to find an aftermarket rev limiter to make sure.

I'm not trying to sound snooty at all here, but I would think the obvious maximum rpm for a stock 968 engine would be the factory redline.

It was 60+ degrees here in the 'ham yesterday, so I took the time to seal up all the openings and took the engine out into the driveway to be cleaned.

Sounds like you need either standalone engine management or a custom built 968 DME chip that will work for your specific engines setup?
If the later than use a known high quality chip tuner that can support or stand bye his work?
Buy a set of new Porsche springs that go inside the Oil Pressure Relief Valve to ensure great pressure readings!

Seems like a complete standalone ECU such as a Motec would be worth it. At that point, is an MSD box completely redundant, or does it still offer useful additional functionality?

Its not really necessary if you have a standalone system, but the price tag of a Motec system is pretty steep compared to around $200 for a MSD box. The factory ECU works really well even on highly modified motors. The most power I have seen out of a motor running a factory ECU was 315 at the flywheel and it didn't have any problems tuning.
