Robert ,Vauxhall/Opel combo 1.7cdti

as a sameday courier covering 90k miles per year I am always looking for ways to save fuel. I obtained a tunit unit. It improved my motorway fuel consumption at 70mph from 43mpg to 45-50 mpg. I have now exchanged it to fit my new 1.3 Doblo van. My 1st 400 miles job got me 37mpg but when I fitted the tunit I got 45mpg doing the same motorway journey.
