Steinbauer modules - Diesel power upgrades

Get up to 20% more torque with a Steinbauer power enhancement module for passenger vehicles and up to 50% more torque with the Defender Kit Turbo-charger upgrade and improve the performance of your diesel engine. Steinbauer modules don't change rail pressure, the performance enhancement is achieved by changing the injection duration. This method is the same way the system was originally designed to operate, also allowing precise fuel control throughout the full rpm range of the engine.
