This 3-Port boost solenoid is a great means of tuning your boost curve through the ECU. For those of you who upgraded your downpipe, this is a great means to control boost through tuning so you’re not running max boost levels from lower to upper RPM ranges. With the 3-Port boost controller, you can safely tune your boost levels at the max-safe levels throughout your power band.
This 3-Port boost controller can get into boost sooner than most comparable units. It is also plug and play for OEM harness which means no modifying the wiring. It comes with a provided bracket to make for a clean installation, and works well with your Subaru factory ECU.
