Knock gauge help


10's here i come
Ok i have a caspers knock gauge but no scan tool and i push my car way to hard. I see every one on here having knock problems at a low boost. I have ran 20+psi boost on 93 pump gas and never get any knock. At the most i might get 1 light every blue moon. Is this gauge working ok or is my car crazy and just does not knock much.

Does this sound right , and can i tap next to the knock sensor and light the gauge up to see if it works.
yep if you tap on the block beside the knock sensor you should get a reading.

man this slow phone conection sucks
im in wv now i miss my cable internet
