I have a Greddy Profec-B boost controller, and I'm pretty sure the solenoid is shot. Is there another solenoid that I can buy and hook up to that controller besides a Greddy?

 

I remember seeing the AEM style in the Grainger book.

 

As long as its a 12vdc solenoid valve, it should work. The only problems you may see is if your controller uses insanely high frequency to switch the solenoid on/off, and more than likely you'll have to do some readjusting. Depending on the coil and such, 50% duty cycle for one solenoid may flow more air than another solenoid.
