Heard a pop now wideband pegged at 10:1

I was pushing it a bit in fourth. Didn't notice the boost gauge but I saw the check engine light come on. Through dsmlink I have it set to come on at 4 counts of knock. I let up on the gas instantly but not before I heard a pop like an intercooler pipe had blown loose. I pulled over to check things and found that all the pipes seemed to be secure. The boost controller source line had come loose so I secured it and got back on the highway. I didn't fix the problem though. As soon as I build 5 lbs. my wideband reads 10:1 and holds there. I have no power when this happens and the car bucks and backfires. I'm going to check the compression, do a boost leak test and check for oil in the coolant and coolant in the oil tomorrow. Anyone have any ideas as to what might have happened or any suggestions?
Thanks

Did your biss shoot out? Do the tests and then get back to us.

I'm expecting you to find a boost leak somewhere you wouldn't expect to.

Boost Leak.

Leaking boost from somewhere.

I got under the car this morning and took a closer look. I had in fact blown one of the couplers loose. It was a small gap and I must have missed it last night in the dark. Fixed it up and the car runs fine. Should have checked more thoroughly before posting. Thanks for the help guys.
