General Maintenance, Troubleshooting & Accidents.
Hey everyone,
As title says my wrx is only boosting 10psi at WOT.
Car was hesitating a lot at higher RPMs, changed spark plugs (hesitation is gone) but the car is now only boosting to 10psi.
Previously the car max boost was 18psi.
I’ve checked for boost leaks and loose intercooler pipes...
