Julian,Ford Transit

I had the Tunit installed to my Transit 90 hp just 10 days ago because the fuel economy was so bad ! To say I am pleased now is a big understatement. Before I got around 360 miles per tank before and now I am getting 410 per tank. The fuel economy was expected but the extra power took me aback. I actually like driving this nearly as much as my Q7 now which is booked in next week to have the same ! Thanks

I would highly recommend Tunit, great customer service. Both the Optimum Plus and Power Pedal have made a considerable difference to my car with regards to acceleration. Considering I can change the settings on the Optimum Plus, I have never actually wanted to and have been more than happy with it on Sport +. Glad I bought these instead of getting a re-map as I can unplug and plug in whenever I want; it’s great!
