Our tuning box systems are completely safe.
We have been tuning diesel vehicles for many years and have extensive knowledge on what settings each system needs for the specific vehicle it's being installed on.
Your engine's ECU (Engine Control Unit) is always in full control of your engine, because we're governed by all the built in safety features we cannot exceed the safe limit for your engine. None of our systems override or alter your vehicle's settings at any time.How a tuning box works

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
