6800 to 8K RPM Bucking
I know issues like this have been covered before; but I can't find this exact issue when I search.
When I accerate hard, to the redline, all is well until around 6,800 RPM until the redline.
I've checked the sensors, etc. on the car and can't seem to find anything out of the ordinary.
(1991 N/A)

bogging (in my personal experience with my car) is always due to fuel loss someway or another.
Also check your secondary injector connectors. Make sure you are getting 100% contact. You might have a poor contact, and they just fail when your rev gets that high.

Let see where to start. The fuel filter has less than 8,000 miles on - The spark plugs some where around 250 miles. The wires are still in good conditition. The MSD is working fine. This hasn't been a problem until recently. I'll check the ignition equipment again just to make sure its in proper working order. I'll also give my injectors a look.

Do this at a safe place and immediately shut the engine off.
Pull the spark plugs - what do you see?
If it's black and "spotty", it's misfiring - most likely ignition break-up.
If it's white and "clean", it's not getting enough fuel.
Also might want to check your TPS narrow-band resistance full open.
Anything over 5.5k-ohms can cause high RPM hesitations.
