This depends mainly on how you drive. If, after tuning, you use the additional power only when you need it, the improved torque will reduce your average fuel consumption by a few per cent. However, if you use the extra power regularly to increase your acceleration rates, you will use significantly more fuel. Under stable highway cruise conditions, you may see up to a 7% improvement in fuel economy.

Not all cars can be remapped. Older models – typically those manufactured pre-2000 – may need their chips physically modified (which involves removal and soldering) rather than a simple software update or remap. The cars most commonly remapped tend to be those with turbo diesel engines. These models will see the most significant improvement for relatively little cost. You’re best off calling a specialist and asking what the benefits are for your particular make and model.

The remap will increase the power output of your vehicle, and depending on how you drive depends on how reliable it is for you. If you go at it harder than usual, you can expect to decrease the life of your engine but likewise if you thrash it without even having it mapped then you would expect this to be the case anyway. The remap does not stress the engine, so it does not affect the longevity, only your driving style. We have remapped modern engines with over 200,000 miles without issue, so it is doubtful that you will get problems.

Tell your insurance provider if your car engine has been remapped. Remapping or chipping is considered a car modification in car insurance terms, even if you can’t see one. So if you don’t inform your insurance provider, it could invalidate your policy. Car engine remapping could mean an increase in your car insurance premium cost. And, even though remapping is increasingly common, some insurance providers won’t cover your car if it’s been chipped.

There are stories of remapped cars flunking their MOT because they failed the emissions test. But this should be fine if your remap is carried out by a reputable firm such as Essex Tuning.

Existing modifications can sometimes bring good benefits to enhancing the software so let us know in advance.
