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

T I P , Renault Espace 3.0 DCI

Since fitting the Tunit, my average fuel consumption has improved from 25 mpg to between 33 and 38 mpg and the performance of the Espace has become much more lively.
