RPM, Temperature, Gear/load, humidity, boost pressure, type of ignition systems and fuel systems you are running? I don't know a whole lot as I am still learning myself. I am just now getting pretty comfortable with the VE table and tuning the air/fuel ratio. I haven't ventured too far into timing yet but know I need to. If anyone can post some more information that would be great. Thanks guys. - Jayson

Well load and rpm are most important. The others are just small variables. There should be a range for the IS stock or with lower compression. LIke Im running from 10 at idle to 25 up in the rpms. Then in boost... I go from the last value of that rpm before starting boost... down to 9 in the boost side. Im still experimenting with this also... like i said before... I need some advice.

As for the small variables... they are ~80 degrees, ~65 humid, ~990 mBar baro.
