Since there are no cels, possible cause:
1) AFM --- yup you are checking the filter
2) Spark plugs + coil paks
3) fuel filter
4) vacuum/turbo leak
5) Worn turbine but i doubt it
My 2cents

As I am doing this the car accelerates extremely slowly in 1st and 2nd (much slower than I am used to) and hesistates/stutters as it rises revs (between 2 and 3k)...at 4k-5k its still accelerating slowly (again, slower than it should be doing this)
I know boost gauges are not accurate by if its any help mine is showing I am hitting my 15psi at around 2.5k
My only guess is either bad batch of fuel or the ecu is in limp mode (not getting any kind of warning/CEL lights)
Car is a 06 wrx, only power mods are a 3" Butler TBE, Walbro Pump and EcuTek tune.
Im boggled and worried
-Shane.
