Description
The advantages of the 2015+ Subaru WRX GrimmSpeed Electronic Boost Control Solenoid 3-port boost control system versus the factory 2-port system are readily apparent during the tuning process. The 3-port system works by interrupting the boost signal traveling from the turbo to the wastegate. That boost is redirected back into the turbo inlet and re-ingested by the turbo using GrimmSpeed’s machined adapter. This is important, as the factory mass airflow sensor has already measured that air and is expecting that your motor will use it during combustion, rather than venting it to the atmosphere. The factory configuration simply ‘bleeds’ the signal from between the turbo and wastegate, which creates a system that is a bit less complex, but reacts more slowly and with less precision..
