The Safest form of Diesel Engine Tuning

Safe, Reliable Diesel Tuning - A Speedhawk Diesel Tuning Box works with your existing ECU to get the best from your engine without risk of damage.
Easily Revert to Standard Tuning - If you ever want to revert the vehicle to standard tuning, you can do this in a few minutes by disconnecting the diesel tuning box. No permanent changes are made to your ECU or engine. This also makes troubleshooting any problems easier, and protects your warranty.
5 Year Warranty - We are so confident in the technology of the Speedhawk tuning box, we offer a massive 5 year warranty. If your unit suffers a component failure, we will replace it under warranty.

The Speedhawk Diesel Tuning Box is carefully designed to help you to get the most from your diesel engine. It works with the engine, adjusting the fuel pressure, airflow and fuel mixture to boost the power and torque. This type of diesel tuning talks to the ECU before it has adjusted the engine parameters. The engine is therefore still controlled by your existing diesel ECU chip, and the ECU will not adjust any settings outside of it's pre-defined safety settings.

Common Rail and Pumpe Duse diesel tuning boxes come with a selection of tuning maps pre-installed, allowing you to select the level of tuning applied. In some cases certain selections (especially the higher ones) can make engines run poorly, with smoke and uneven power delivery. Which setting works best with your specific engine depends on it's age, condition and history. However, as the tuning box is still going through your existing ECU, no permanent damage occurs, and turning the diesel tuning setting down until the best setting for your engine and driving style is reached allows you to obtain the full benefits of your new diesel tuning box.
