Focus St underboost
Hi guys.
Basically I had a dyno on my car and found out the car isn't boosting properly. So we replaced the solonoid. And messed with the actuator. Got it working perfect it made 311bhp.
Then after the dyno I realised the car wasn't hitting full boost its sitting at half.
I was told it could of blown the recirc valve with the pressure a common fault so I went and brought a forge uprated recirc valve fitted it and it's still only
Hitting half boost.
Could it be down to the actuator? If so how would I set it up?
Or could it be something else.
It does though an error code up saying turbo under boost??
