This is the one I have on my set-up. Wastgate spring is at 8psi and when I turn the switch on, I am at 11psi. A little pricey but works very well and simple to install. I've seen a few "build your own" single stage controllers so search if you are on a budget. I think Turbosmart is the only company that makes a single stage boost controller.

 

use a choke cable for carburators run it to your wastegate
