Pinging is a result of the timing, or lack of. And the flat spot is carburettor adjustment. Fine tune those two aspects and you're good to go.

They are the two most important ingredients when trying to make optimum horsepower.

1. Do not remove the vacuum advance. It will not interfere with a supercharger, but more importantly will serve to hold the advance plate fastened.

2. Reduce the overall timing. Easiest way to do this is to set static (idle) timing to 0-4 degrees, which will reduce high RPM timing to ~25-29 degrees. Further tuning involves modifying the advance weight slots inside the distributor.

pinging could be too much compression more likely...
and I hear the DGAV can have a hard to find lean spot with a blower...

You can also go twin screw more efficient and extra using less capacity
