my car wont run in the high timing tables EVER...
The most timing I see at WOT is around 18-24.5 mostly closer to the 19 degree mark.
In my older car i programmed the two tables to match each other then removed timing where needed.
debating on going back with updating my ls1edit to this new PCM or going with the HP tuners.
I get knock around 91-100mph often.
Injector duty 85-91
IAT always 29-31
until i get an editing suite anyone have any areas to check?
i use only 93 octane

Lots of factors for timing not being what you want. Check your IAT timing retard. If it's hot and your IATs are high, you will get lots of timing yanked unless you address this table. Same with engine coolant temp spark retard. If you're getting knock, the octane scaler (over time) will drop your timing to reside primarily in the low octane spark table.

Thanks
These are the values at WOT
IAT - 84
ECT -188-190
Later in the run got to 192 (I have been contemplating the 160 Tstat)
On a regular driving run. not much KR at all maybe every now and then for a blip or two then nothing. I noticed at WOT at least 50% of the time I get 1-3.5 degrees of knock. Any other time it NEVER hits the high octane tables. I have run it down to 1 gal avail and filled up with 93... drove around for 15 minutes then l0gged. Same thing low timing tables.
Thanks for the tips I may just order he 160 stat and see if it helps
