BMW F435D (2015) Developed 308 to 400 bhp with torque 465 to 570 Lbft.

The performance gain, following the remap on the late 35d variants – is astonishing – this all thanks to Celtic Tuning and their commitment – re-inventing such a torque delivery within safe limits for such vehicles.

Another mile stone with F-Series BMW, sees us now being able to tune/communicate with the ECU via OBD using various GENUINE tools (previous ECU removal since 2009….) a huge leap forward, in terms of the speed involved for the works time to complete the job.
