Mounting 02 sensor for A/F sensor, where?
 

Anyone know the best place to mount the 02 sensor for a Greddy A/F gauge?
Gauge came w/ an o2 sensor and a bung, directions said to mount in a location where egt between 400-800 C ideally 500-700 C Ide like to mount post turbo if possible but i dont know what egt's are in that part of exhaust. No cats 3" turbo back. Thx in advance

EGT's before the turbo go over 800 deg F specially under load my EGT guage is right before the uppipe and im getting some high readings there under load so i dont think thats a good spot for your guage
if you have a helix downpipe you can use the wideband bung thats right after the turbo?
