I sent datalogs in this past Saturday, haven't heard back yet. I will try calling today.

I am running 93 octane gas, no E85 local to me unfortunately.

You should log fuel trims for bank 2 as well as bank 1 to see if they are both maxing out.

This will help rule out a faulty injector in bank 1 causing this issue.

You can also try increasing the cell values for open loop fueling in the user adjustable table.

Here is what I changed mine too:
I am logging both banks, they are just overlaying one another (you can see the blue and black line to the left before they both max out). The car ran fine before installing the procede (I was JB4 then JB4/meth, but no meth now). I also don't want to change the map yet as I feel that there must be something causing this.

Both are logged.

Right, the downpipes have been installed over a year with no issues.
