Is it the same as the Jumper and Ducato?
They share platform and mechanicals, sold under three brands. Our experience with one applies largely to the others.
Is a remap worthwhile on a large van?
Yes, especially when running loaded. The extra mid-range torque avoids working the engine hard on gradients and at motorway speeds.
Can I disable the AdBlue system?
Not on public roads: regulations require emissions systems to be operational. These files exist for specific applications; ask us before ordering anything.
