What tune do you have on ur car?

I'm planning to re-tune my Bimmer and wanted to see what everyone else is running lately. What's your current setup? I'd appreciate on hearing which tune you're on, the pros and cons you've experienced, your dyno numbers, and what fuel you're using. I have a 2020 430i (B48) and I'm currently weighing a few options: Bootmod3 (BM3), MG Flasher, a custom tune from a top-tier reputable shop here in Brazil, or a custom tune from a newer local shop (All the tunes beign STG2). If anyone has a similar car, I’d really appreciate your thoughts! And if you guys could also make recommendations i would appreciate it!
