F2X m235i F22 idle issue (Big Boost 3.3 kit)

[ganque]

Hi everyone,
I have a 2014 m235i F22 with Big Boost kit 3.3 on a XDI-35 HPFP, Fuel-it Stage 2 LPFP and the BPM4 fuel module, and of course fully bolted...
The car started to give me some rough idle issues, car runs excelent under WOT without any issues.

When the issue first started we replaced injectors 4 and 5 since I was having some specific Cyl #4 & #5 misfires.

However the issue persists with the only DME error for AFR too rich.
Logs seem to me ok under WOT, but it's the idle that's driving me crazy.

3rd gear WOT (Couldn't make it all the way to the top)

Any help would be greatly appreciated

could you check sparkplugs? maybe try run OEM spark plugs and see the idle.

no idle log ?

Also, looking at the logs - you're running quite lean to be honest. what fuel is that ?

EDIT : ok, just saw it's e30, i wouldn't be comfortable with such lean AFR, maybe it's just me..

Your spool and boost seem very low starting from 1st gear. Is this a slow spooling turbo? I thought these spooled faster than a ps2.
