sr20det please help.........

ive been tryin to figure out what could be wrong with my car for a while not... when i hit full boost it starts to hold back and jerks u back and forth... at first i thought it was my turbo but after taking out the turbo looks fine and has barly any play in it at all, while taking out the turbo i realized that one of the gaskets were [censored] so i bought a new one and replaced it but still the same problem... so next i was thinking it could be my knock sensor being [censored] up so the computer could have been retarding the timing when i hit full boost because of the bad knock sensor but today i checked the ecu to see what code it was throwing out and it was code #55 which is no problems... i know my ecu is reading right because when i unpluged the knock sensor then it started to read code #34 (knock sensor) im also running really really rich, fouling my spark plugs left and right.. so now im thinking it has to have somthing to do with fuel or ignition... dont have a fuel pressor gauge so i cant see where its at... i have no leaks on any of my piping so thats not it for sure... does anyone have any kind of thoughts on what it could be? any ideas at all would help.. maybe my fpr? ITS NOT INTERCOOLER PIPING
