It's called "British Specialist" and is located north/north-east of Japan Auto Parts, north/north-west of the jaguar dealer, south of aston martin dealer and south/south-west of British Independents (TVR, Caterham, Lotus dealer).
If you draw a straight line between jaguar dealer and british independents, it will be ca. halfway along that line.
Ok, to make it even easier for you: When u exit the Jaguar dealer, take a left, follow that road and after the first bend (a left bend), the tuner is on the right.

Good enuff 4 u?
