Tunit was founded in 1998 with the purpose of offering the relatively new concept of “Diesel Performance Tuning”. The company saw the disadvantages of existing tuning methods on the market and took the basic principle of enhancing an engine with adjustable, externally fitted systems, added unrivalled customer service, support and after sales and ensured that these values were upheld by its network of licensees and representatives.


Today the company has built a modest worldwide representation and has a healthy and prosperous growth without the aid of investors. The company comprises of a core staff of around twenty who run the Sales, After Sales, Service, R&D and Marketing departments. Our Head Quarters are based in the town of Chorley, in the heart of the industrious and prosperous North West of England.


As an established leader in the market of performance tuning, we are neither assuming nor neglectful of our position. Only by our continued commitment to product development, customer service and the planet’s green future will we guarantee our future prosperity.

The company is moulded by our customers’ requirements and in turn we endeavour to provide and maintain the highest of standards. It is our aim to provide an ever increasingly better service and product to all customers on a worldwide basis and challenge and improve what is good to be better.
