My 335i was happily running 27.x and running really well. A blown board meant that my dealer took me up to 30.x. It became laggy and rough running.

Upon insistence from me - they reprogrammed it with 33.x and ticked on the wastegate retrofix and my car is running BETTER than before. Smooth and fast.

I'm sure the ticking noise is there - but I'm not going to push it as the car is running so well....
