I wouldnt trust them. Took my evo7 there to get checked out after getting a rallie art ecu fitted they told me it was det and told to send it back. Phoned woodford garage to tell them what happend. They told me they have never heard of that happening before. They gave me russ that used to work at wallace he checked the car out and there wasnt any faults at all. So ive never been back. Also ive had problems with extreme at whitburn.
