What are the benefits of using the APEXI boost control kit? I have an ej20g td05h-16g with Power FC and datalogit, why would I want to buy this as opposed to controlling boost with the factory stuff?
The factory map sensor for the EJ20G can only accurately measure up to ~17 psi. If you use the Power FC to control boost and want to run more than the map sensor threshold pressure, you will either need to use the Apexi boost control kit or another form of boost control (manual, electronic...). That's the only reason to use it.
