They run 25-45hz so it may or may not be compatible with your current controller, ive seen guys run them from 2- over 30psi with a 2lb spring

Edit: part number for the valve is MAC 46A-AA1-JDBA-1BA the are typically $65-70 although haltech aem and turbosmart will sell you the same valve as an upgrade for $120-250
that valve plus a turbosmart eboost2 = WIN
Edit2: you need actuators something like this to use a 4 port solenoid on internals

full race also gets one from forge might want to ask them about it. also turbonetics sells a more affordable sealed dual port actuator
also note the GFB Gforce2 should work with the four port valve i mentioned so for roughly $150 you could have bought the solenoid and two of the sealed 7psi 2port actuators and run all boost your turbos could supply.
