interesting i mistakenly assumed the x5 got the 369lbft tune. I am now curious if the component version matches.
the 369lb/ft number has been the upper limit for the B58 in multiple versions
-355hp: MPPSK for the first gen B58 and std for 2019 X3 M40i
-335hp: supra/euro Z4
-382hp: M340/2020 X3 M40i/USA Z4/supra upgrade
