My car is knocking under full boost also. Stock boost on a hot air car. Running 93 octane.

this looks like your chip is locking the BLM at 128, the idle BLM at 150 is maxed caused by a lean condition. O2 mv at 170 also indicate to much airflow not enough fuel. I would say you have a pretty bad leak...either vacuume or exhaust.

I would have to agree on the bad leak, either vacuum, or pre turbo exhaust leak.
Both the BLM and INT are maxed out at 150. Very bad.

Actually I can probably point you in the right direction, the most notorious leak on these cars is the drivers side header, take a cardboard tube and listen for ticks...

passenger side header is leaking on the primary closest to the firewall. And i had two vacuum leaks one on the compressor housing and the other was in the boost gauge line. The car runs alot better now.
