At the end of last year we heard about Varra, a British company with a new range of ‘plug in’ tuning modules. With offices in Australia, India and Russia, Varra has a website offering full details of suitable applications for the UK Market. The company claims to have tuning modules available for around 3000 diesel vehicles, with a petrol version being launched later this spring. These modules work by altering the fuelling at certain rpm levels, thereby changing the power delivery; either for more power, or better economy. The Varra module can be manually adjusted, and fitted can be a DIY process, although fitting agents are available. Products have a two-year warranty.
