What do you aim for on a light truck?
Sustained pulling capacity when loaded and contained fuel consumption per hundred kilometres, which is what shows up on the operating cost sheet.
Can I disable the EGR?
Not on public roads: regulations require emissions systems to be operational. These files exist for specific applications; ask us before ordering anything.
Is the work reversible?
Yes. We always keep the original ECU file, so the vehicle can be returned to its factory configuration.
