We recently enhanced a BMW 435d, pushing its factory limits from 300bhp and 614nm to an impressive 380bhp and 782nm. This transformation, adding an extra 80bhp and 168nm of torque, was achieved through our precise custom tuning of the Bosch EDC17CP45 engine and fine-tuning of the ZF8 gearbox on our cutting-edge 4WD linked Vtech dyno. Join us as we delve into the details of this powerful upgrade, ensuring a perfectly safe and thrilling experience on the 4-wheel xDrive system.
