Jb4 support tell me that: Best to use maps we've developed and tested. For the fuel I'd stay on map3 for now. For higher octane fuel, map5. And they do not want to adjust the map 6 Best boost i reached on map 2 and 3 is 17psi if I'm lucky 18 is this enough?

Any one try to adjust map 6 with jb4? And which map you use for daily drive and race
