KCPerformance is constantly developing stages for a growing range of engines. One of our favorite engines is Mercedes' OM642. This V6 3 liter diesel is very powerful and yet economical, it's a engine with a lot of potential and that is why we have a very wide range of tuning options for this motor.

Our reputation is why this brute E 350 CDI Coupe came to us. He was looking for more power and KCPerformance was the answer. The DPF was removed from under the car and cut open in order to empty it. Everything was neatly welded back shut and assembled back under the car. The software was modified so that no DPF errors can ever appear and also the EGR was closed through a software modification. Then we upgraded the software to a KCPerformance chiptune stage 2+ in order to increase the power to 310hp with a huge amount of torque 615Nm. The lambda sensor was deleted from the software together with some other fault codes.

The keys were handed back to the customer and after a test drive he was very impressed! This upgrade changes the OM642 engine from Dr. Jekyll into Mr. Hyde, it's very economical and when you kick in the gas pedal the car takes off like a beast! You can imagine what we can achieve with going even further to a stage 3 or stage 4 tune...
