EGR Delete

EGR delete is free when you purchase a remap, or £30 on its own. If you're not sure if you require EGR delete, please read here.

Stage 2 Remap - 150-155 BHP

As the Peugeot 406 2.0 HDI does not benefit from electronic Turbo control, you will need to fit a mechanical boost controller, along with an intercooler and a free flowing exhaust system. We can then tune the car to have more than 150 BHP and more than 360Nm of Torque. It is possible to make a 'limited torque' remap file, this may be required if your clutch is worn or you do not want to upgrade it. An organic clutch with an up-rated pressure plate is recommended to go with a stage 2 remap. You can expect to see economy gains of 3-5 MPG on average.

Online price: The online remap is just £99, Postal remap service: Send the ecu to us via post £150. or use our Drive in service: Complete drive in service with diagnostics and road testing £200.
