HDI Tuning Ltd specialise in advanced ECU software programming solutions for the Peugeot and Citroen HDI engines. All remapped software is developed and written in-house through years of intelligent research and development.

The files we produce have been tested extensively with the safety of your turbo and engine at mind. We maximise the power output of your engine whilst reducing fuel consumption and remaining within the safe limits of your engine. At HDI tuning we will not be beaten on our price, quality or customer service. We are proud to offer the best remapping service for the HDI engine, and this can be seen through our many happy customers.

What makes HDI Tuning Ltd different to other tuning companies?

HDI Tuning Ltd specialise in only the HDI engines (and also the Ford TDCI models which use the HDI engines). After 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.

There are many companies which offer remaps for hundreds of different cars with generic power change figures at a bargain price. Unfortunately these companies buy in their generic remapped software from large european file distributors for around £30, with little or no understanding of the changes made to your ECU software. These companies then upload the unknown software to your ECU and hope for the best.

Even for expert tuners who know how to write their own remap files, it's impossible to offer the best remaps for every single engine and ECU combination due to the amount of time it takes to decode, develop and test remaps for each engine. All the remaps we sell are the result of owning our own vehicles and testing for thousands of miles. We only sell remaps which we've developed and tested ourselves personally and can guarantee excellence.
