Proform 850 dialing it in closer

Wellllll TPS works good...........o2 meter.....not so much. so much for the solider trick.
It didn't mess up near as bad or quick until i install my exhause extensions, or lengthened them. think i will pull them back off when i get to the track.
The only reason i put them on was to be able to read launch o2's and they need to be longer for that.......................
only full throttle reading.
If the remove or the exhaust extension fix the o2 screen lock up, then it just to close to the header aka heat issues . If it make no different.....well then i'm still looking for the reason why.
While let you know what my finding out tomorrow night.
