Afr
Mine was showing lean yesterday so i turned up the box too bring back to low 12's. It was really boggy so i put my new spare probe on and when i pulled the same hill my afr was down too the high 10's. So needless to say my probe was giving false readings. When i dropped my attitude numbers back to normal sled rocked again. So long storey short apparenty they can just give you funky readings. My old probe had around 900 miles on it running 100LL

What are your egts reading when your afr gauge is all over the place.
Don't have egts. I am thinking I should get a gauge just for these instances.

I use to only run egts but since I installed an afr it really shows the relationship between the two sets of gauges and makes the fine tuning that much easier.
I like running both as well. On my last turbo m8 AFR ran 12.5 almost all the time while egt ran 1250.
