Hey guys! Could someone help me figure out something more powerful for my jb4 n54 335i?
I currently have map 6 at 22psi on e30 and around 500hp, while that’s enough power I would like a tad bit more and some more smoothness into my tune, any recommendations for the values I need to set for the different settings in map 6 config?

Current Mods:
duel cone intake
charge pipe
HKS BOV
arm downpipe
Xhp stage 3
Stage 1 fuel it lpfp
Bms sport cooler valve

like others commented, use a backend flash with your JB4.

From what I'm learning now, JB4 dont adjust timing directly. So you need to flash a map with proper timing to add more power over the JB4 settings.

I was dealing with a well known tuner here, but stopped since the car was doing 240whp.

Contacted Terry, and right now on 350whp and going up ! Nothing wrong with the car, only setting.

Unfortunately, there's not a ton of tuner to help you with a JB4+BEF(MHD).

You can use full MHD and still running JB4 only for monitoring (map0)
