I made my own vacuum solenoid set up in the boost signal>WUR circut using the summit racing digital rpm switch and a bosch vacuum solenoid that is programmable so it doesn't use pills or chips, and it cost half what the MSD switch goes for.
It works perfectly.

Have it programmed to ground the vacuum solenoid @ 4500rpm using a relay.
I also wired a tiny light in parallel with it up on the side of the center console next to the LC-1 status led so I can see that it is working.
