Our Neetronics branded MAC valve electronic boost control solenoid not only allows better control over your boost, but it also gives you the flexibility to choose between a 3-port and a 4-port set up.
A 4-port boost controller allows you the ability to run higher psi without having to max out your wastegate spring. Should you have an external wastegate, or plan to switch to one, we offer our boost controller in a 4 port so you can take full advantage of more refined boost control with your EWG. It is also ideal for boost by gear applications.
