2. What sort of vehicles do you work with?

We can re-map most of the following vehicles and machinery, depending on make or model, the key is if your vehicle has an electronic injection pump or common rail fuel system:

  • trucks
  • buses
  • tractors
  • agricultural vehicles, harvesters etc
  • cars
  • utes

3. Will a remap damage my engine?

No, not if the job is completed properly (which we guarantee to do).

4. Can anything go wrong?

Yes. If the technician doesn’t know what they are doing, they can:damage the vehicles engine control unit

  • cause the vehicle to go into “limp mode”
  • cause a dangerous “over-boost” in power
  • cause damage to expensive engine parts (including the drive-train)

For these reasons, we strongly recommend that you be very wary of cheap remapping solutions, plug-in products etc, especially those that are promoted online. These products are not a substitute for a comprehensive remapping carried out by an experienced, qualified remapping specialist.Our technicians are fully-qualified and experienced and we guarantee our results.

5. Do you offer any guarantees?
