My Renault master 2.5dci has improved by about 3 mpg, when doing 1000 miles a week its a great saving.

My main purchase intention was to extract more performance for my car. Tunit provided me this additional performance that I was looking for. Soon after that, I began to see a slight reduction in diesel consumption and this was interesting. I adjusted my driving habits, taking into account the additional performance, and the fuel savings was more regular. It seems that I now have the best of both worlds - performance when I need it most, and low fuel consumption at other times. Tunit was really easy to fit and its adjustable performance levels allowed me to experiment and find the best compromise between drivability, performance and fuel economy.
