NA AFR Readings
*If this needs moved, please do so. I assumed more responses in FI section*
So I have a turbo kit coming soon. To save some hassle, I went ahead and installed my UEGO and boost/vacuum gauges.
Here are my "stock" readings, was curious if anyone else was in this ball park
Idle ~15.3-15.5
Cruise~14.2-15.5(bounces a lot...normal?)
WOT~12.5(works its way to 12.5 near the upper RPMS) but it also seems to "accept" 13 as well. Haven't made a lot of runs yet to see
Also I have noticed under medium accelerations is when the AFR is most stable. cruising that thing is none stop bouncing...
Has anyone else taken data on thier NA tc?

seems about right. that is where my tc was when it was supercharged roughly. but your stock a/f's should be fine since they were tuned by toyota. only way your readings would be off is if the o2 sensor for the a/f gauge was misplaced and getting a bad reading.

No I have a megan Header...MY stock one is pretty much shot...
Plus I'm going turbo soon... So this seemed like a logical place, far enough from too high of temps according to AEM?

You could be as close as the primary O2 sensor in actuality but for a longer sensor life (negligible) it's recommended to be put farther away. I have mine in the very beginning of the mid pipe because my S-Pipe was going to be changed out soon when I got the bung welded in.

I just went with what the AEM instructions said. they call for 36 inches if turbocharged, so i guesstimated, and threw it in where it was easy to get to...
I think it will be fine though...
