This is the BMW 435d with X-Drive and the owner of the car is no stranger to us. This is the second car he has had tuned with us, and the last car was identical to the one he has now. As soon as he got into the new car he realised how dull the car is in standard form, so booked straight in with us for our CustomPro software to improve drivability.
As the graph below shows, the car now holds torque for much longer and the improvement in high rpm power is incredible, especially considering this car is a diesel!
Power gained: 72 bhp
Torque gained: 91 nm
