I've recently been having issues with the readout of my AEM wideband in HP tuners. The curve is very choppy, esp when I compare it to the readout of the WB O2 on the dyno (which is a MUCH smoother curve). Right now, the sensor is placed about 8-9" from the left side turbo in the downpipe. My thinking is that there is so much backpressure located in this section of the stock H pipe (this is a 100% stock LS2 motor, running 14-15 psi with small twin T2 GT3076r's) as well as too much heat generated by the turbo that the sensor cannot accurately read.

Here is a link to the datalog and config file of what I am experiencing - I feel that by moving the sensor back another 12-24" this should fix the issue. What do you guys think?

Why not just move it back then ? They dont like getting too hot, and pressure can affect the readings.
