Where can I get hold of an air soleniod to...
 

.......swicth between 2 levels of boost.

I want to run the normal high boost and then switch to 7psi or wastegate pressure for her in doors. Anyone know of a soleniod that will do this without having to buy one of the dual stage controllers?

There's a way of doing it with an electric one, a good use of the bright switch!!! There's a page on the net somewhere, I thought I had it saved, but it would appear not!
