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!!!
