Anti-Surge Boost Control Solenoid V2 (523) by Company23
Game changing boost control for turbocharged Subarus utilizing electronic anti-surge technology. This solenoid allows tuners to more precisely create your boost curve (increasing spool and horsepower) by not detuning your car to eliminate boost oscillation.
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
- Allows RPM/load dependent boost control
- 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
- Does not require retuning for temperature/season changes or extreme changes in elevation
- No need to worry about partial throttle/full boost during closed loop
Please Note: The valve housing and solenoid valve were revised to enhance the dynamic range. The calibration was also changed to make it significantly easier to tune by matching the boost curve range of C23's standard boost controller.
Applications
- 2008 - 2014 Subaru WRX
- 2009 - 2013 Subaru Forester XT
- 2005 - 2009 Subaru Legacy GT
