The tunit has increased the power and fuel consumption of my Fiesta by at least 10%. I used to get 58 mpg and have recorded 65 mpg when drivng steady for a whole tank. This was done on dual-carriageways into work.
Nigel,VW Scirocco 2.0 TDI
With regards to the Scirocco I can make a number of observations since the Tunit has been fitted:
· The fuel consumption has improved with the journey back from Silverstone showing 61.5 mpg travelling at an average of 80mph the car having 3 passengers plus me and a boot full of luggage. The overall average is holding at 53.5mpg being approx 8% better than before the unit was fitted.
· Performance wise the pulling power has noticeably improved giving a sense of urgency to the acceleration. The set up of the Scirocco with its lower profile wider tyres and sportier suspension seems more than able to cope with the increase and I would suggest that it could manage a little more. This is born out with the introduction of the 260bhp S3 version recent shown in the Top Gear Mag.
· The drivability is still as good as before the mod.
