Frequently Asked Questions

 

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

The standard manufacturer tune is a compromise of hundreds of factors. Most of all the manufacturer has to ensure a high degree of engine reliability across the worldwide market taking into account factors such as:

During testing, manufacturers ‘tweak’ the tunes constantly to achieve the required results for individual tests, this compromises the overall smoothness of the original tune. EAPJ Performance Tunes are optimised for European driving conditions. As long as the manufacturers service schedule is adhered to there is no reason why this extra power can not be ‘unlocked’.

 

How will the emissions be affected?

All EAPJ Performance Tunes are tested to ensure that they comply with UK emissions law.

 

Is the tuning process reversible?

Yes. In the unlikely event that you require the EAPJ Performance Tune to be removed, the process can be reversed without any side effects.

 

Are there any physical changes to the vehicle?

No. EAPJ Performance Tunes are ECM software downloads only. There will be no physical evidence that the engine has been uprated.

 

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 bodykits and different alloy wheels. Some insurance companies will add a premium to your policy, others will not. EAPJ Performance Tunes are invisible and it is impossible to detect that the engine tune data has been modified.
