Well, airflow will vary based on mods and if you've messed with the pcm's airflow calcs.
Timing advance- usually shoot for 26-28 deg. at wot
Throttle Position- 100%
LTFT- you want them to lock at 0 at wot

Thanks for the response. Is it normal for my timing advance to vary a lot?
At part throttle it ranges from high teens to 40 degrees. At WOT the lowest reading I have is 9.50 and the highest is 30 degrees.
The only mods are a Granatelli MAF and a Flowmaster muffler.
At WOT my air flow rate is 0.3 lbm/s and my LTFT is 25.
