For the record I have YET to see ONE Contour run lean - from the factory, even with mods. Most the time they run pig rich so you don't need to be randomnly adding fuel without knowing what the AFR is for starters.
Case in point I tuned 3 SVT's at SZ All 3 ran at about 11.5:1 at WOT, after leaning them out to 13:1 (all 3 were using S-AFC's) the averagre gain in hp was about 9hp!
You've never modded a Zetec? 
Even with mild mods/no mods the Zetec will run around 12.5:1- 12:1 A/F.
