14.7 is if the fuel had no ethanol in it. Most vehicles nowadays show a sloped stoich table or a table that is around 14.1 or 14.2 because most pumps have E10 in them.
If the table is sloped from say 14.7 down to 9.0 it could be because it's a flex fuel vehicle and as the alcohol % rises the stoich value goes down.
Without seeing the file or a screen shot that is off the top of my head. Side note, outside of some sort of power enrichment/cat over temp protection or whatever else the computer will want to achieve stoich at all times.

If you don't post your tune and logs when you have questions you aren't helping yourself.
if I could figure out how to screenshot it I would send one. its not a table its just a box with 14.08 as the setting right now
Oh I see, then yes that is what your stoich is always commanding.
I used to the GM side on the newer controllers where it's a whole table instead of just one box. The older GM controllers used just a box as well for stoich too.
