Also been on the phone to Dave at Sere today to explain the N75 issue and how I thought the new E valve was faulty due to the car not holding boost properly when fitted but being better once the old F valve was back on. Dave is sending me another E valve in the post to try, before I even get the old one back to him

now thats customer service
