Recent software upgrade 11.2019/70 changed transmission and exhaust note

I have an mpe and I noticed the sound changed. Less low end growl and more loud bangs under hard acceleration.

Normally when you tapped the gas it would pop a few separate times, but now it's one shorter brrrp sound. Definitely a change.

Transmission in just sport with engine is sport+ is smoother. Overall the transmission feel slightly tighter and better.

Car feels about the same in terms of speed and acceleration.

Anyone else have any ideas, I'd love some data or dyno numbers.

If you like your car louder don't upgrade

I upgraded and notice no difference in the burbles/bangs.

However, I do have the exhaust flap permanently opened up. Maybe they changed the actuation of the valve?
