Vehicle manufactures are in a tough position here, they have to build one vehicle for all drivers - it's a bit like a nice suit off the shelf; it fits well, it looks smart, but it's not custom tailored for the end customer. Tuning is just the same - if you own a fleet of vans you may want a speed limiter or rev limiter added to help save your fuel, yet another customer may want a little more power to help with towing or heavy payloads. These sorts of changes can only be made once the vehicle is built and the customer needs something other than 'off the shelf.'

Not necessarily, in fact in many cases quite the opposite. Even on a performance tune, if you continue to drive the car in the same way as you did before the upgrade, your fuel consumption will probably improve. Of course if you have a track day motorsport tuning map installed on the car, and you are driving the car under the conditions in which full on motorsport tuning is intended, you're likely to find a slightly reduced MPG figure. In just about all other cases though our tuning will improve your vehicle's fuel economy.

Whilst the upgrade in many cases is undetectable, the responsible and correct answer to this question has to be "yes", your insurance company should be notified of any modifications including tuning. However, the good news is many insurance companies do not penalise you for upgrades of this nature, particularly if you're tuning for increased fuel economy.

We take great care to ensure that all of our modifications have no detrimental effect on your car. In a lot of cases the economy tune actually helps to extend the life of components, such as the clutch and gearbox, by making the delivery of the power far less aggressive and smoothing the overall drive of the vehicle.
