Just a VPW 15HZ oscillator driving a TIP-30 power transistor.  Use it to 
run the Buick GN boost solenoid and install it on the boost line to any 
wastege.  Gives you control from factory wastegate set boost (12 PSI)  to 
25PSI (on the GN's anyway... Not sure what other vehicles are running for 
boost stock.)
The way the "plumbing" end of it worked it:


Intake manifold  ---------{}-T------Solenoid-----Air
                              |
                              |
                              Wastegate

The {} is a restrictor.  The solenoid bleeds off a portion of the boost 
getting to the wastegate... the more it's open, the more boost has to build 
before the wastegate operates... when the solenoid is closed, the boost is 
stock.
On the Buick GN's, the dealer sells the factory T with a couple short hoses 
and the restriction is built into the T.  You could cobble your own and 
play with different sizes for the restrictor to come up with whatever boost 
you like.
