The TD5 from factory is set incredibly conservatively from a fuelling perspective. Our Stage 1 remap is how we feel the TD5 should have left the factory.

A Supernaut Stage 1 remap will see the Td5 become more responsive, much sharper and a good increase in both low down torque and overall power.

We write our maps with a few unique features. The TD5 has a fixed geometry turbo, so our maps ensure we get it on boost as soon as possible. We also know that some powerful maps can result in jerky throttle response where ours is very OEM in feel.

No hardware changes at all are required. This is a simple and fast software change in the ECU.

Our work has been proven on our own and customers vehicles over many thousands of accumulated miles, through structured development trials, customer feedback and testing and validation, where performance figures, drivability, and long-term reliability are all optimised as part of the development process.

Our own TD5s run a dual map system featuring stage 2 and stage 2+ switchable maps, both of which have more than enough power for our applications.

Note: If you are unsure if you have a NNN ECU please refer to your engine number. This will start with 15p for NNN ECUs. As a guide, NNN ECUs came in around 2002. If in doubt give us a shout. Mapping for older MSB ECUs is coming soon.
