Alan,Mini Cooper D

Dear Sirs

On a recent long weekend to the Wye Valley in our new Mini Cooper diesel, fitted with your new chip, we covered 358 miles. On the journey down there we averaged over 78mpg.

For the whole weekend, on one tank of fuel, we averaged 74.7mpg, driving at normal speeds, not especially for economy.

The vehicle regularly averages over the mid fifties, just running about locally. We are obviously delighted with the vehicle's performance and frugality.


Glenn,Skoda Kodiaq 2.0 SUV

I've had 4 units since 1998 and all have delivered smiles per £ . From a 1.3 corsa to a 2.8 jtd Campervan that went from 22mpg to 27 mpg . My Kodiaq 190bhp DSG 4x4 mpg average has gone from 37mpg to 42 but up to 50 when motorway cruising . Real shove in the back when foot down as well even when towing my 1.5ton caravan.
