What is the best tune for BMW E92 M3?

It want it to be class A cause I like to use it for tag and stuff, have some grip as well, but also I want it to do good when you do those “unofficial” drag races in tag with people that like to do that. I was racing some guy in the 2014 Civic and my Civic was AWD and a good drag car but he was neck and neck with my halfway down the runway and then just completely passed me in his e92. So I’m trying to find the best tune for it but I want to be able to edit it, like the ratios and what parts go into it so I can see how its done. Is anyone willing to share any info on this?

Also you can check out my BMW E92 M3 Design! It’s based off a realistic police car. Most realistic design out there!
