HDI Tuning specialists

HDI Tuning Ltd specialise in the Peugeot and Citroen HDI engines plus the Ford and Volvo TDCI PSA derived engines. After 8 years as a registered UK Limited company and 10+ years of working with just the HDI engines we know them better than anyone. All remaps are the result of months or even years of research, testing, and development upon the engine they are applied to. This ensures the best possible performance and driveability from our remaps.
