Unplug the JMS and see if it still occurs. I see your sig says LT4 fuel system, does that include a ZL1 in tank pump as well?
Yes, it has the ZL1 in-tank pump as well. I'll try that unplugging the JMS and see if the code pops up during WOT.

The code started popping up after the JMS add on and e85 tune. BUT due to my previous tune, Ted (JRE) stated that my previous tune still had a whole lot of stuff on stock settings and that I had a lot of setting for DTC readings disabled from the tune.

During the dyno tune, no issues. When I drove the car back home no issues. It was maybe a week later, I did a long WOT pull up to 128 and the codes popped up. Cleared codes and did 3 more pulls like that on 3 separated days and codes pop up again. Car feels fine overall. Did a data log, sent it to Ted, he did a revision. I uploaded the revised tune and seemed fine after 3 pulls to 130. And during this time I was still on a 56% e85 blend.

A week later after that, I have a track day and code pop up again when I'm WOT on the straightaway hitting 110. But I kept pushed through out my 20 mintue session. Car felt fine.
