your cat is plugged or your muffler is plugged, my 04 did the same thing, i cut the cat off and put in a piece of pipe, runs like a top n spools much faster

did u take everything out of the cat or knock a hole n it? i just knocked a hole in mine and the outside finally broke up and plugged up the exhaust, pull the exhaust off your turbo housing at the motor and start it up and take a quick drive, dont get real wild with it cuz it will get hot n a hurry! but back it out on the street and mat it to the floor and see what ur boost does then, thats how i narrowed mine down to the exhaust 100%
