Question Tuning a e200

I have a 2020 e200 with a m264 engine that i want to tune, and need help with a couple of questions.

1) if i tune my engine with dinan sport tune meant for an e300 is that ok?
2) if it is ok would it give me e300 power with a tune (280-ish ig) OR e200 power with a tune (240-ish)
3) also 98 RON isnt available in my region can i still run the race preset on 95 RON? What are the possible outcomes of using 95 RON?

Im sorry if this is alot but i cant find anything online, thank you to anyone that can help
