I think we found the problem right there, a dying MAF.  Mine was doing that earlier this year, I noticed that the boost gauge only reads 7 psig max (instead of the usual 9 psig) and power seemed a little off.  Took it to the dealer and they found my MAF was reading low.  A stock (unchipped) car should have MAF reading around 200-220 g/s IIRC.
