[Boosting35d]

Guys,

Any ideas on what to do next, car is low on power low end, it's very hesitant low end like the engine is starved of air/not breathing properly

Live diagnostics show air intake is off the scales, reading 3 times the max value when under load?!

2007 e92 335d 140k mileage - remapped, egr and dpf delete (gutted)

New map sensor
New boost temp sensor
Cleaned MAF with electrical spray
Air filter reasonably new
Forge red intercooler pipe
Smoke tested - no boot leaks
New pressure converters and bracket
New turbo change over valve/switch (small valve that switches between big small turbo
Vac lines all replaced

Car keeps coming up with 41AA error code which points to MAP sensor, yep, I have already double checked fitment

Please help!

Thanks

I had a crap map, after remap by BW Chiptune in Hayes, the issue cleared up (they diagnosed it relatively quickly)
