its been 3 key cycles and about 68 miles

However during WoT I "believe"(someone correct me) that the calibration (LTFTs STFTs) are ignored and just a (MAF/Fueling)table is used. So if your LTFTs(read calibrations) are not 0 then the WoT will be running lean/rich from the nominal design... If you LTFTs are positive your MAF +10 you sensor is low and need to be increased to account for the correct amount of air... so during WoT you might be running a little lean...

At least this is what I think happens... I have been wrong before... correct me ?

from what ive read, your right, i just wanna know HOW lean lol, if im below a 11.3 A/Fr, i dont care, i just dont wanna be running too lean at WOT
