Why do the manufacturers limit the power output of their engines?

The standard manufactured file is a compromise of hundreds of factors. Principally, the manufacturer must ensure a high degree of engine reliability across the worldwide market taking into account factors such as:

  • Fuel quality
  • Different servicing schedules
  • Different operating environments, such as altitude and terrain
  • Local legislation with regard to power output and emissions

During testing, manufacturers 'tweak' the files constantly to achieve individual results for individual tests, thus compromising the overall smoothness of the original file. A Re-Mapped file is optimised for European driving conditions. As long as the manufacturer’s service schedule is adhered to, there is no reason why this extra power cannot be 'unlocked'.

How will the emissions be affected?

All Re-Mapped files comply with UK emissions law.

Is the tuning process reversible?

Yes. In the unlikely event that you require the Re-Mapped file to be removed, the process can be reversed without any side effects.

Are there any physical changes to the vehicle?

No. All Re-Maps are ECU software downloads only. There will be no physical evidence that the engine has been upgraded.

Are there performance figures for all Re-Mapped files?

No. It is impractical to produce graphs for all engine variations. There are simply thousands of variations in maps. The power output of an engine will depend on age, oil condition, temperature, air pressure.

Are there any insurance implications?

Yes. Most insurance companies require you to notify them of any modifications to your vehicle. This includes modifications such as stainless steel exhausts or different alloy wheels. Some insurance companies will add a premium to your policy, others will not. Re-Mapped software files are invisible and it is impossible to detect that the engine tuned data has been modified.
