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.

Alan ,VW Bora 1.9 TDI-PD

My VW is smoother when accelerating through the gears, pulling stronger from lower revs. Motorway driving is more relaxed with the extra top gear pulling power. Very pleased with my tunit.
