    I think it's a pump issue. I have the revised valve.

    err, I have a regulator valve. Not sure what gasket or valve cover they are talking about. However I have never noticed abnormal boost pressure. Mine is always consistent. I hit 21ish and then taper to 16ish at redline w/ my k04

    Those guys are not supplying proper information. All of our US model cars already have that upgraded pressure valve. The pump is what is needed.

    Re: Important Info On Fuel Cut Out APR

    I was supplied information on upgraded fuel pressure relief valves by a company in europe about a year ago and discussed it with APR. They advised at that time they were also looking into these valves and were supplying them with the k04kits. I had the valves at that time and as I looked into it, I found that all US model cars we could find including early build date B pump equipped 05.5 cars already had the upgraded valve. What is needed is the pump and injectors.

    cheers! mike
