Steve,BMW 318D 2.0
Just had the Tunit V-CR fitted to my 2008 BMW 318 Diesel. Have to say that service and after-care from the company is excellent. Dealer fitted it in 10 mins, took me through de-installation etc and even knocked £20 off the bill. My car is now a 320DSE- torque, economy and smooth engine pull have all improved. Icing on the cake is a 3 year warranty, removability between cars and a PART-EX facility. Superb-buy this product!!!
Lee,Citroën C5 2.0 HDi
Hi Daniel, since the fitment of the Tunit V-CR unit to my new Citroen C5 I have noticed a marked increase in fuel economy, performance and refinement. At a steady motorway cruise the average consumption has improved from 40mpg to in excess of 50mpg. Performance has also increased and the added midrange torque makes overtaking swifter and safer. I am delighted with the result, especially as I fitted the Tunnit to enhance performance rather than economy. The added benefit of being able to transfer the tunit to another vehicle in the future is the icing on the cake.
