Our tuning box systems are completely safe.

All our tuning boxes have been designed to be installed and removed easily.
Especially useful if you would like to remove your tuning box system for maintenance or servicing without trace.
Due to the nature of how our tuning boxes connect to your engine they remain at all times behind your ECU (Engine Control Unit), this crucially means your engine is always in full control.
ECU Remapping is very much like an update to your mobile phone, its a change in software.
Whilst this method results in noticeable performance changes it can involve a lot of intrusive works which cannot be reversed easily. With one of our tuning box systems you can achieve the same fantastic performance gains safe in the knowledge no permanent changes are being made and no trace when you choose to unplug the system.Tuning Box vs Remapping
