i think your 6th port isn't opening up. If not, make sure your intercooler lines are tight and snug. I had the same problem, under boost, it would hesitate and bog like crazy, then i found a loose intercooler line...(the big one on the right side that goes straight down looking into the engine compartment from the front of the car).

Your injectors might also be clogged. Start with the easy stuff first like parkplugs.

turbos are 4 port, not 6 port....

I'd look for vaccum leaks first.

damn, i thought they were 6 port, cuz i while back when i had this problem someone told me it seems like my 5th and 6th port prolly isn't opening, so thats what i was going by.

Sorry for misleading you, just trying to help.....
