Check air mass meter is plugged in ok as may have come unplugged & yes mass air can affect this as affectively its telling ecu air flow & adjust fuel accordingly.

1st thing i checked
still the same when unplugged

 

[NHN]

Urm sounds like maf is ********, can you check if its getting any flow registering in measuring blocks with vcds?

sorted was this lil fukker
unplugged it car started and ran
checked MAF was spot on.

Boost sensor, maybe not a good idea to run car without that working, as that effectively would not show boost levels correctly, maybe ok but I wouldnt want to risk incorrect boosting transmitted to the car systems.

im not running it
was unplugged to find the fault
left it in the garage till i get 1 in the morning.

Fair enough
