I have had my cars at PE for Power Runs and Servicing never had a problem down there. Also they have built a few Focus turbos (6 IIRC) that had issues but they sorted them out everytime, Customer service when you are there is excellent.
Chris and Ian who look after the dyno are top blokes and no matter what you have (even if its german or spainish) they are more than happy to help.
