Stock boost levels on 335is

I'm trying to find the stock boost levels for a 335is but I keep seeing 8.5 for a regular 335i. Anybody know ?

Overboost is around 12-13 psi I believe.

yep, sounds about right. I seem to recall seeing 13.5 but maybe that was dinan

I think stock targets for all n54 and n55 is 9psi. I know n55 is 9psi. check the mhd threads for n54. or Google stock n54 datalogs which will show the targets

Regular boost is in the 8-9psi range like all N54s, but overboost on the 335is is 11.5-13.5psi range, depending on conditions, as mentioned. There are time and RPM limitations to how long the overboost will be targeted for.

12-13 keep in mind ECU does not target boost PSI which is why there is no set value for stock boost
