Do they come lean from the factory or rich? I've got my 02's reading 860-880mV. I just leaned it out on the top side a little compared to stock on the stoich afr WOT divider. Truck is stock with grandpa exhaust and k&n drop in. Some serious mods![]()

Mine tried to maintain stoich until it hit PE, then it went to about 11.5:1.

They run lean until PE comes in, which is way too late but doesn't hurt anything m
Then the engine runs rich when cot comes in.
Adjust PE mode and turn off cot.
Those o2 sensor readings sound just right. If they're working correctly they can give u a very good idea on afr

All stated is correct. My crewcab read 11.8 from factory just leaning it out it picked up rpm band and smoother power
Yea i've got PE settings good to go. I leaned it out very little from 4k up and could tell a difference in power and engine sound. The IDC got to about 68% then just about flat lined the last 2k rpm's. I'll have to borrow a wb from someone.
