Subaru Boost Controller Manual:  Download

Features:

• Game changing boost control for turbocharged Subarus utilizing patent pending electronic anti-surge technology.
• Eliminates common and annoying internal and external wastegate flutter! 
• Allows tuners to more precisely create your boost curve (increasing spool and horsepower) by not detuning your car to eliminate boost oscillation.
• The top Subaru tuners have proven the benefits of the Company23 anti-surge boost control solenoid on stage 2 cars up to 650whp track beasts!
• As simple to tune as a basic 3-port boost control solenoid.  Very tuner friendly! 
• Easy installation with included OEM quality mounting brackets and electrical connectors.  "Plug and tune" for all Subaru models!
• CNC machined and anodized 6061 aluminum housing is completely sealed for a lifetime of use. 
• Boost conroller uses a custom 3-port solenoid designed by Company23 and manufactured by MAC.
• 6mm(1/4") CNC machined hose fittings.

Advantages over other aftermarket 3-port boost control solenoids:

• Eliminates wastegate flutter.
• Prevents oscillation in the boost curve.
• Makes more horsepower and torque when compared to a detuned map focused on eliminating flutter.

Advantages over manual boost controllers:

• Allows RPM/load dependent boost control
• No need to worry about partial throttle/full boost during closed loop.
• Does not require retuning for temperature/season changes or extreme changes in elevation.

Advantages over standalone electronic boost controller or standalone ECUs:

• Retains OEM reliability and driveability.
• Is "plug and tune" easy.
• Significantly less expensive.
• Less complexity.
