Drove my car around town yesterday and realized my cruising AFR is really only 14.5-16. Not as high as I thought.

I'm hoping to get the wideband back up in the exhaust system where it is suppose to go, cause I dont think I am getting consistant A/F readings. If I get it far enough in the end of the tail pipe it seems to be more stable. So it might not be
in the 17-18 afr like I think it is and more in the upper 15's to 16's cause it sure does start nice and idles great and goes down the road without any hits and misses if you know what I mean.....doesnt hickup or anything anymore. Not over heating and finally doesnt smell gassy going down the highway for the car following it. I dont know if it is the right way of doing it but I have it setup to run a little richer for under 800 rpms for start up in the VE table.97 Comp T/A #161 out of 164 LT1 383 stroker, TPIS/AFR heads, JE pistons, 9.3cr, extreme energy comp cams 224/230, Howards billet rods 5.85, Callies dragon slayer crank, 2 bolt mains converted to 4 bolt billet, Mildon oil pump, MSD opti, 6AL, boost retard, HVC 2 blaster coil, BBk 58mm, 50lb injectors, 3200 stall.

WRONG.........fruther back the sensor the more inaccurate the reading.........sensor should be within 12" of the header collector

X2 also watch out for reversion with open header or systems that are short.
