We have a subaru imprezza. If has just started making a blow off valve sound and boosting real hard. It does not have a blow off valve. Is this going to cost us! Is it the boost controller!

Most likely a hose has fallen off the wastegate actuator or has perished and has a leak.
Dont drive it hard, you could end up melting pistons.
