YAAAARR!11 Possible cheap Hobbs switch type thingy!
 

Digikey part number 384-1012-ND is what I just ordered, adjustable pressure switch 1-4 psig, $14. There are a variety of different pressures and ranges available - easily found searching digikey for "pressure switch."

They come in 120/240 VAC and 30 VDC flavors - I'm not sure if those are requirements or capabilities SO DON'T RUN OFF AND BUY ONE JUST YET. Joey will let you know how his works.

i saw some on ebay for sale. the guy had a few diff PSI ranges too

So what are you planning to control with this thing? Wastegate soleniod? VTEC activation by boost pressure instead of RPM?

Older (mid-'80's) GM low side AC cutout switches are preset to 30psi, adjustable up (useless) or down to, ---- I guess 0psi. New they're cheap, from the junkyard they're free.

Also used to control water/methenol injection for forced induction vehicles.

vw makes an electric on way valve. when you give it 12v it opens the valve.

There are a whole bunch of purge solenoids and other useless crap on a Honduh that can be used for the same thing. This is not a pressure switch.
