I have two manual boost controllers laying around. They are brand new. They can hold well over 25 psi. My buddy runs one on his WRX. He's running 13.0, 18 psi, no problem. I'm not sure what it's called, but it looks exactly like the Dawes Device boost controller. They sell theirs for 42 bucks. I'm asking 30 shipped with instructions and vacuum hose. I want these out, please buy these. email me at bentz626@yahoo.com. I accept paypal and money order. thanks
