Desensitizing GM knock sensors

[Jim Wilson]

  Hi Guys,

  On my 92 LT1 383 Vette I have a CR of 9.4:1 and a Vortec Supercharger (10#
boost). I have tried 101 76 Race gas, have changed the spark map over 4000 @
100KPA to as low as 20 degrees Adv. and still show a 7 degree knock retard
spike anytime in boost (over 100KPA). What do you think about trying to
densitize the Knock Sensors. If so what is the best way, teflon tape?
                                 Thanks, Jim
