Hi Lucasborka, i share you my datalogs:
Idle:
https://datazap.me/u/vetus/log-17113...27-28-29-30-31
WOT:
https://datazap.me/u/vetus/wot-stage...29&zoom=22-196
Stage 1 MHD N55 EWG, Catless, Wagner evo II FMIC, Turbo inlet MST V2, MPPK lower airbox, GFB DV+ diverter valve.
your logs seems to me normal, at idle STFT is always "sinusoidal" even the timing between the 6 cylinder have a small offset. Pattern that i see regularly on my logs. In conclusion mine and your logs are pretty similar.
Your manifold Boost is just a little bit below the boost target.
what engine modification do you have?
