REVIEWS

Douglas, VW Passat 2.0 TDI

I have had a tunit unit fitted to my VW Passat estate now for about 7 months, and it's great. Performance and fuel economy as well. What more could you ask for. Well Done Tunit, and Best Wishes for the new Year. I hope your sales of tunit units rocket so fast that you can't keep up with demand.

Happy Christmas to all.

Andy, Landrover Defender TD5 2.5

The Tunit has transformed the feel of my Defender. Quite frankly, brilliant!
