limited to 9 psi

Post by turbo970 »

well now my subie will only boost to 9 psi. had a boost leak test today and they found no leaks then they put it in drive and held the brakes to make a load and they said its hissing at the actuator. so if it's truely bad would this work.

Which turbo do you have installed on your car? What are you using to control boost?

How much boost were you making before your problems occur.

Do you have any codes stored in the ECU?

Are you using the stock boost control, manual boost controller, or aftermarket electronic boost controller?

Which coupler?

If it's ballooning under boost, it may also be leaking under boost.

I'd probably wait and see if that fixes things or if you need to turn it again sometime in the future.
