Is this real knock retard? I am pretty sure...just looking for another opinion...
I was getting 4.5 degrees of knock retard at WOT (on my Malibu...) with the stock timing tables with 110 degree intake temps. Since it takes regular gas, I tossed in some premium along with some octane booster (supposed to raise octane up to 15 points or 1.5 octane), so I was running with maybe 94+ octane (I ran 70 miles to mis everything up and flush everything out of the lines before my last log) if I am lucky and my knock retard consistently dropped to about 1 degree or less. Are the stock tables just really agressive?

maybe it was just the high temps pulling timing out. i know in the ls1 it has tables for 100+ where it pulls timing, im wonderig if thats what is going on?
now that i have been paying attention to it i can hear a lot of cars spark knock in the heat, might be shitty 87 gas?

There is a IAT advance table pulling timing already. So that would mean that the IAT advance table is not pulling enough timing, except even when it is cold(er) outside I was still getting plenty of knock retard.
