This option is designed to improve economy of turbo diesel engines. By reprogramming the torque limits on the engine at lower RPMs you’ll notice improved economy, as well as benefitting from additional performance.
At high RPMs the software upgrade will encourage shifting up through the gearbox which enables the engine to keep running in its optimum window. This is the most popular choice, particularly with fleet owners and where extra MPG improvements reflects on bottom line profit.
Our most popular remap choice, offering the best mix of power and economy in virtually all turbo diesel engines.
De-restricting the engine by opening up the torque and power range leads to a better driving experience while returning an improved fuel consumption figure.
This is also really well suited for motorhomes and campervans.
