I had a reprogram done at Lincoln Show and I have carefully kept the mpg figures, from actual mileage and fuel put in the tank, not an onboard fuel computor.
1 Average mpg before usual driving technique 56mph average speed on open road 28 mpg.
2 average mpg after reprogram same speeds and techniques 24.8 mpg with not a lot of difference in pulling etc.
All done on similar mix of roads.
I had it done as I am looking for the most fuel economy possible, but could have bought a fair bit of fuel for £260,
Conclusion it was a waste of resource. The van was probably set up to maximise the economy at the 56mph point by Ford and the programmers have removed the peak there probably put it up to 80mph.
Ahh well!! live and learn.
