Got Code 52: Knock Sensor... Options

[gtfc115]

Ok so just recently ive been getting a CEL and the car has been hesitating under full boost at ~4k rpm. it also stumbles pretty often when it's just idleing.

the most recent changes ive made are my new 3" exhaust, raised boost to 13psi (for 1 day), gapped my plugs down to .028, and capped my turbo pressure sensor (to get rid of fuel cut and raise the boost.)

now i get this code 52 and pretty bad overall performance...it was running so well, so something i did messed it up.

Just ordered the ATS racing GM knock sensor kit. is there anything else i should do when i change the sensor? what if that doesnt fix it? (im sure it will though)

and now that i think about it, i bet i know what did most of the damage. before i got my exhaust done, there was only 1 bolt connecting the cat to the rest of the exhaust and it was blowing hot exhaust gasses almost straight into the area where the sensor is...im sure that wasnt good for it.
