As above. It wont be a maf issue, they run pretty much fine even with the MAF unplugged and on a S2 map alot of the time the MAF is useless as your flowing more air than it can measure so IQ is only set by the ECU on load (TPS) and revs and it guesses how much boost your likely to have.
If your feeling sluggish and cutting out its probable either LP pump, rail sensor or the regulator in the HP pump.
Take your fuel filter out and look for gold filings in the bottom and its a sign the LP pump is on the way out
