Hi been having a bit of a fueling problem recently, recently had new fuel tank, fuel pump, filters etc, car is running much better but surges quite badly on accelaration, both on boost and off boost (more noticable on boost)

it seems to hesitate and then surge (accelarate) then hesitate a bit etc,
i have fitted a new maf sensor and as i say, had the fueling sorted so i can prety much rule that out, i was thinking maybe some sort of problem regarding air intake possibly o2 sensor, any ideas?

Cheers
