I only do small mileage most of the time but it does save money

Stuart,BMW 520d

I am very pleased with the outcome of tuning my new car. I have had the unit installed for a couple of months now and have seen a real performance increase as well as miles per gallon when driven economically. Would highly recommend Tunit.
