Essex-based TDI-Tuning closes 2014 with a 37% growth year-on-year and more demand than ever for its long-established diesel tuning boxes and other services.

The company’s plans for 2015 include further product development for diesel road cars, and a continued focus as a brand name for design and manufacturing of tuning boxes specific to agricultural vehicles and motorhomes.

The company’s growth is made more poignant by the deployment of its four-man technical team: led by ex-Ford Technical Director Steve Legon, the division is one of the largest for a UK-based tuning box company, giving a very strong product line-up and very quick response to any development opportunities.


Unlike the common hard-core strand of diesel tuners who search for ‘headline grabbing’ bhp figures, squeezing everything possible out of the engines, even to the detriment of longevity, reliability and consumption, TDI-Tuning’s products maximise performance (power and torque) and drivability without compromising the engine, whilst at the same time reducing consumption by up to 20%.

TDI-Tuning boxes do not require the engine’s ECU to be re-mapped: they are plug-in devices with no need for technical knowledge or special tools by the consumer, are easy to fit, are removed with no trace of their presence, and the vehicle does not have to spend hours in a garage.

TDI-Tuning’s modern facilities and state-of-the-art technology make the company one of the very few UK businesses to preside over the entire process: from product design and development to manufacturing (which takes place in Germany, to exacting standards) and final assembly, fitting and testing back in the UK. “We are one of only a few companies offering twin channel tuning boxes, and the only one to use an independent review service to rate our products,” says principal Graeme King.

With export activities becoming more and more pivotal to the UK manufacturing and economy’s growth, TDI-Tuning’s trading with Europe and other foreign markets, like tuning-savvy Japan, is particularly important. “Japan is both an exciting and challenging market for us,” continues Graeme, “because it is a sophisticated arena which appreciates our products; with strong home competition there, it is hugely satisfying to see TDI-Tuning’s market penetration in Japan gain momentum.”

Ambitious, but well-grounded plans of expansion for TDI-Tuning also include further growth of its dealer network (already +120% in 2014 vs 2013).
