Take it slow as your fuel trims will need to re-adapt. You have both e85 and jb+ which cause you to run leaner and it uses fuel trims to adapt. You guys may want to check your long term fuel trims and ensure you aren't at 30% ( I assume to be max; good chance I am wrong) or another round number in that range.
Meth can also jack with fuel trims as you are changing your mixture on the fly.

I also watch my coolant temp. No use doing logging runs if you aren't up to temp as the DME limits boost in that case.
For fuel trims, they constantly adjust to give you the correct amount of fuel based on the fuel you use and small differences from car to car. As long as they aren't maxed, you are ok. They get maxed when you add e85 (lean it out but raise octane) and the jb+ (lies to DME in order to raise boost) and the fuel trims are used to adjust.

If you rode it hard right off the bat, I bet you ran lean and were knocking. Gotta give it time for the fuel trims to adjust.

The only code I've ever seen has been a partial throttle air mass code. Just an annoyance code some models need a CAN tool to disable. Lowering the dial position can also keep it off. Could also be a defective JB+ or some other simple issue. Bottom line is the CAN Tool is strongly suggested as a companion tool with the JB+ to read the code and email those specific details in for support. Without knowing the actual code it's impossible to provide anyone with technical assistance.

Couple of logs from tonight. Everything appears to be good at 2 o'clock with the roughly 30% E85 mix. Someone mentioned to keep an eye on the long term fuel trim and that appeared to hover around 0 to -5 if that makes sense. Anyone that could help under stand the readings on that would be appreciated. Disregard the missing boost reading.

Im really curious and plan to keep an eye on this but I will also be running 70/30 91/E85 as the gas station 2 minutes from home has E85 availible and one out by work is planning on adding it.
