On my 1990 GXL, my VDI opens at 5500RPM. You should feel it when it opens, the engine will rev faster and you will feel a slight extra pull from your car. It also makes a whinning sound (at least on my car)
As for how high you can go, I really don't know. Don't want to get into a lean situation when the fuel cuts and risk blowing the engine.
I usually shift at the redline. My car pulls till 8500rpm with my mods.

I have hit something that might have been fuel cut at 8.6-8.7K as well.
The car is not usually making useful power at that range unless it is modified . . .

The aux ports on the other hand would be consistantly at 3800 given more than 1/2 throttle, and engine at opperating temp. It wouldn't activate unless the temp gauge read right at its normal position.
