Performance Engineering Without Compromise

Bespoke ECU Calibration • Classic Carburettor Tuning • Lucas 14CUX Specialists • Rover V8 Performance • Rolling Road Optimisation

Performance engineering is far more than simply installing a different calibration file. Every vehicle is unique, with its own mechanical condition, modifications, component tolerances and performance characteristics.

Why Choose Turner Performance?

For over 50 years, since 1975, Turner Performance has specialised in engine management, performance diagnostics and bespoke calibration for modern and classic vehicles.
