I have a 2007 R56 MSC, strangely with no sport button

So, because of no sport mode, I was thinking to do chip tuning remap at the local branch of ATM ChipTuning (https://www.atm-chiptuning.com/). I put it on the dyno, they said I can expect ~+30bhp...

Still, there will be some things that will still be missed since I don't have a sport button: the steering will not become sharper and I believe that there will be no pops&bangs, like on MCSs with sport button. But, after reading this forum, I've noticed that some people were complaining that pops&bangs are gone on their MCSs after a software/firmware update?

Anyways, I wanted to know if they DO offer to do pops&bangs together with remap:
1. does that increase fuel consumption?
2. is it bad for the engine, turbo, exaust, etc?
3. do you still have it on your software-wise up-to-date MCSs?

PS I did not do a de-cat, but AFAIK, MCSs have pops&bangs even without a de-cat?
