02 zo6 timing tables in a stock truck on 93 octane? has anyone done this? i have an 05 avalanch that i want to try this on. Stock other then a k & N air filter. I put 93 octane in the tank and now need to load the new tune, just wondering what others results were as for gas milage, towing and all around performance.

Uhmm... no! That will add around 10 degrees of timing under WOT... and little to nothing at cruise. You can't just take a timing table from one vehicle and throw it in another. The timing has different adders in the truck than in the car...

You need to dig a little deeper, while figuring out what
you want from the truck.
Trucks do a lot of stupid stuff, from the standpoint of
performance, in pursuit of stuff like towing fuel economy.
Like for instance holding off PE for a long while and using
a low spark advance to keep from ping.
Throw a 'vette table at that situation and you'll have a
ping fest a-comin'.
Now maybe you're prepared to live with poor towing MPG
if you're sport-truckin'. In which case you'd go and fix up
the fueling to be more like a sports car, and use timing to
match.
But it wants some thought and care, not just slap on a
random bit of "sounds like a good idea".

Not a good idea IMO. I made my timing tables from scratch adding where needed and smoothed it to my liking. I looked at other timing tables when I first got the software but it doesn't yield any gains. It takes time and logging to do it right.
