MHD banging when lift off throttle

Hey guys just want to know if this issue is just me with the latest 3.10? When on hard throttle and lifting will cause a bang and jerk motion/hard cut. On MHD stg 2+ and DCT who stg3. Never had any issues before the release of map switching. Regret updating...

Which map are you on? V10? V9? V7?

Do you have burbles on? Exhaust setup?

A "jerk", like the car setting back, when letting off throttle at a higher rpm after hard acceleration is pretty normal. Result of engine braking. The bang I would expect too if you have burbles and a decently loud exhaust.
