Drove the car a little harder then usual last night, and now I don't build boost unless i sit in first gear foot to the floor. It'll hesitate and not wanna go, sit at 5500 rpm and then it'll finally catch. I can hear the turbo spool, but it wont give me anything. I also have leaky exhaust (looking for new mani/downpipe ATM) but the leak is no worse then usual. I checked my plugs, they were fouled pretty good. Unfortunately the part store doesn't sell BKR7E where I live. So I wire brushed em and stuck it back in.

Tune is a little off, but the thing that I cant understand is, it just started happening. What should I be checking?
