I'm in the market for **upgrading** and I know that the stock pistons don't like detonation when going with heavy mods...anyone have any pictures of spark tables/EFI Live tunes with spark tables from a turbo application.
I have efi live and I have been doing the tuning myself, finally got my sd tune down and the car is running great.

I made a note to myself a few months ago that CAT3 posted an '02 automatic STS 8 psi tune to Horist's repository. I don't have a link, but that should be enough info to get you started. I'll be searching for it in a few weeks myself... :)

Use the Spark map to your advantage, It will show you and make your tables for you.....
Start with a stock 2002 Camaro table, Then, you add 2 degrees to the whole thing,
Do a log and make a kr on rpm vs gm/cly the table then records any single .00 of knock, then, you transfer and subtrack any you see on that table, the, you add again 2 degrees to the whole thing,
This way, it will move up the low spots and keep the others down.. Usually 4 or 5 is all that can be added... As you see that should keep you at about 20 degrees for your 5 lbs of boost.. So, that follows the safe math also... 2 Degrees per pound. Your peak timing on that motor should be 29-30 NA....
