still getting knock retard w/race gas

[plan Z]

alright i'm running 116 right now and still getting a bunch of knock retard. the timing tables havent been messed with that much and i even pulled timing in some places. does this mean that its false knock? what should i do now? i already readjusted the rockers btw.

It's very possibly false knock, do you have an LT4 KM? Can you tell how much it's retarding your timing?

Headers hitting the floor pan?

wow......116 is a leaded gas.....I'm willing to bet your O2's are fouled now also.

yes i have an lt4 KM, the o2's are still reading the same as they have (i have new ones but i was waiting to put them in till after i ran the leaded gas). the headers are no longer hitting the floor pan. my bullet muffler is hitting on one part of the floor in the back but thats it. I have the pcm set to pull 6 degrees max for knock retard and it is pulling all 6 degrees (normal driving). what do most people do when they have false knock?
