Are u blowing any smoke, check engine, rough idle, if u plugged the pcv's off completely might be a bigger issue piston rings or something of that nature

where are your breathers mounted? your intake isn't connected to the valley cover or valve covers anywhere, correct? doesn't sound good if it was running fine and started this all of a sudden. do you have a wideband?

Yes I have a wideband, I don't think there is a breather on the valley cover, both breather are on the each valve cover

I was thinking if I messed up the rings because before I put the turbo on it I had just a small 100 shot of nitrous but the motor only had maybe 45,000 miles on it
