Stock Boost for 2020 M550i?

jason526 · 12-15-2022, 03:39 PM

I'm planning on hooking up a JB4 and it says Map 1 adds 4 LBs of boost, just wanted to know what the peak boost is at stock?

A broader question for those of us with pre-LCI G30s: Is there an accurate tool available for displaying turbo boost? I have the OBDLink MX+ but it appears to read too low.

Stock may be 13-15 depending on temp/elevation
