'I would just like the thank your director for the advice on the the help he gave me when purchasing a dump valve for my Golf GTI. After phoning Turbo Technics in Durham and not getting the advice I was after I got it from you and with prompt delivery. The item worked superbly, and I also found a split in the rubber that your director said I should see to so I followed his advice and purchased that as well and now my car drives as expected - Thanks again!'
