tuned BMW 435d Gran Coupe.

A nice little improvement on this already tuned BMW 435d Gran Coupe.

 

We managed to squeeze another 11bhp at the top end whilst lowering the EGTs by around 150°C average!

 

We also carried out an xHP Stage 3 gearbox tune to improve shift points and all round driveabitly.
