Hi guys, the boost of my car is bouncing from 12 to 15 psi under WOT whereas target is 18.2psi. It never reaches this point. The logs show that wastegates % oscillate too, both of them at the same very moment. I will add info about my car and also the logs (datazap link + image).
My assumptions is either solenoid in bad state/failing or turbos in bad condition but it is just an assumption and I dont want to throw money on something unnecessary. I have so much rattle, but a lot. I hope you can guide me. Thank you in advance.
My car:
135i n54 6MT with MHD Stage 2+ on 93
Dual Cone Intake
FMIC
Catless Downpipe
Chargepipe + BOV
Silicone Inlets 2"
LPFP Walbro 450
Also replaced almost everything can be maintained, brand new with less than 1000 kilometers like:
Every single gasket on the engine.
RB pcv
O2 sensors
LPFP sensor
Sparks
Coils
Turbo seals
Waterpump and thermostat
Alternator
Battery
All said, here I attach the link of the log.
