Ok so my cat went bad. Bought some aftermarket cats. The mechanic says he stripped out the threads on both upstream 02 sensors. He can get O'rellys supplied O2 sensors that are not Ford Factory brand. It that ok with a tune? Or should I order and wait on them from the dealership?

I would get oem

No way to tell what the scale is for lambda vs voltage...sensors can be different

Some are 0-5 volt some are .5-4.5 volt so the ecu will or can see a different reported voltage for a certain lambda

That's what I was afraid of. Thank you for the quick reply. Only had minutes to decide.

I used NGK/NTK O2s when it came time to replace the OEMs on the Edge.  No performance issues thus far.  I do know that some time back there were issues with Chrysler aftermarket sensors having the characteristics AJ described.
2007 Ford Edge SEL, Powerstop F/R Brake Kit, TXT LED 6000K Lo & Hi Beams, W16W LED Reverse Bulbs, 3BSpec 2.5w Map Lights, 5W Cree rear dome lights, 5W Cree cargo light, DTBL LED Taillights

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!
