A MBC allows you to run higher than stock boost levels by preventing the wastegate from opening at its rated pressure. It does a great job at this but if boost is available under the MBC setting it will give you that full boost. So for instance, you set your MBC to 18psi because from 3000-6000rpm that's what you want. But then say you get detonation with 18psi when you are at 7000rpm unless you are below 16psi. With a MBC, you do not have this control so you are forced to run 16psi through the entire rev range. With an electronic boost controller you could run 18psi from 3000-6000 and 16psi at 7000rpm because you can tune the boost map in the ECU which will allow you to run the maximum amount of boost at every given rpm. This gives you more power throughout the range and better control.

Revolutionizing the EVO boost solenoid market, we have created model specific install brackets that allow you to directly fit our Boost Solenoid into your EVO for a factory fit. No more Zip-tying! We give you the factory fitment you have been waiting for. Staying with the OEM fitment theme, our Boost Solenoid uses a EVO style wiring harness so you can simply unplug your OEM solenoid and plug ours in. No more cutting the oem wiring and crimping wires together!

Also new to the EVO boost solenoid market, we have used ultra low-profile hose fittings to keep the unit as small and clean as possible. The hose fittings are nickel plated brass so you don't have to worry about them snapping off like the plastic hose fittings!
