Dennis, VW Sharan

With a Tunit you are in a higher gear everywhere you go

Bruce, Vauxhall/Opel Vectra 1.9 CDTi 150

I have recently fitted a tunit to my Vectra 1.9 CDTi 150bhp. I cannot believe the results, because not only has it improved performance more than I expected, but also, even with a heavy right foot, I can report an extra 6 mpg around town, increasing to 8-9 on a journey. Well worth the money.
