Hi Folks

Apologies if this has been covered but I can't find much talk of it.

I have a 2007 335i with a JB4 ISO running the MHD back end flash (1-6-16). I have terrible jerkiness which feels like fuelling being cut completely when changing up at anything greater than 90% throttle. My car is an AT and I always use 99RON fuel in the UK. I have the Alpina gearbox flash.

Should I try the desensitise knock sensor option? I'm a bit concerned about the potential engine damage. How likely is that?

Thanks in advance!
