Hi guys,

I'm having trouble with my N54 335 and was hoping someone could help shed some light on my issue. Would be great if someone more knowledgeable could look through my log?

Basically under WOT the car hesitates around 3500RPM - 4500RPM. Just almost like power is down for a moment and comes back. No jolt, no codes, no lights. Feels lethargic and down on power. Generally 3-4th gear, not as often in lower gears but also not every single time. Resetting adaptations seems to help.

I have attached logs (MHD stage 1) and see the boost TARGET is repeatedly low on many pulls when this problem occurs. No codes to pull. Why the target is low beats me. Never had this problem before and it's always boosted fine.

78k KM, Alpina A/T flash, new HPFP, LP fuel sensor, VANOS solenoids cleaned, BMS OCC, DCI, vsrf cp, RB PCV valve, MHD stg1

I have searched high and low to find a solution! Nothing seems to address low boost TARGET that I can tell. If I'm lucky and the target is high, it has no problem building boost to the set target. I wonder what inputs have an effect on DME boost target. STFT bank 2 seems all over the place?

Thanks in advance for your help, these forums are such a wealth of information and absolutely love my new car!

Okay so have cleaned the TMAP/MAP sensors, done the valve cleaning and reset all adaptations. Then logged.

Note the STFT??
