I have not heard great things about BBR to be honest.fwiw http://www.morego.co.uk/index.php (BBR GTi) are reputable with generally good prices across the board (bar some applications which cost between £1-2K lol).
You can also look up RICA Ecu engine tuning (very popular amongst the Volvo tuning scene and on Volvo's the results are amazing).
