I just thought I would drop you a quick thank you message for the Tunit you supplied me recently. The power difference compared to standard is amazing on my car. The power delivery in 3rd and 4th gears is really good. I think I?ve shocked a couple of other drivers recently who were already driving quite powerful cars !!! I?ve set the Tunit on setting 9. I got 500 miles on my last tank of fuel and that was driving ?enthusiastically?  I was only getting about 400 miles to a tank previously. Kind regards and many thanks.
