On the Nwbombers site there is a thread about using a pressure switch and a electronic valve to control the wastegate so it won't crack open at lower psi, they have seen improvement in low to midrange torque because the gate isn't opening to early, a electronic pressure switch measures boost and sends a signal to a electrnic valve to open and the wastegate will open, I 've looked at hobbs pressure switches and valves from peter paul but I'm not sure how to get power to everything , does anyone have experience with this kind of stuff

 

You can use a manual boost controller that allows adjustment of the boost, above stock, and also doesnt let the wastegate see any boost until the desired boost level is acheived, then it "pops" open.

I made the system. It is very simple and effective. You can landine me tomarrow at work.1-800-575-0229 ask for Brad.
