why too much bost. standard car! what's the cure?

 

probably is your boostsolenoid dirty, you should try to clean the hoses to the turbo and wastegate. If this doesn't fix te problem you probably have an air leak. I think you can find plenty of topic's on the subject fuelcut

 

I had that and my boost control valve had to be replaced... £300

 

good news ! fitted boost cont.valve jobs a good-un only cost me £25 though from local salvage yard.
