Car is an Alpina B3S Biturbo
VTT Stage 2 turbos
AMS fmic
AR catless dp
Forge DVs(leaking??)
ER Chargepipe
JB4 G5 ISO + BMS Meth kit - although running map 0.

I was thinking if it could be boost solenoids/DVs or something totally different.

At partial throttle car runs great, also at WOT when it's fairly cold (oil at 90 degrees celcius) When it get warm (105-120C) Then sometimes the boost fluctuates at WOT.

Look at this log:

It's very irritating

Boost leak most likely. Your pwn is all over the place.

I'm so fed up with it .. Where should the PWM be if it isn't a boost leak?

This is with meth add 65: http://datazap.me/u/lfelunden/meth-a...g=0&data=1-4-8
