Have you checked out your lpfp? Dirty fuel filter or the stock in tank pump might be shot since it’s not meant to run higher ethanol content.

I haven’t honestly but wouldn’t the issue be after the direct injection fuel pump since its not pressurizing enough fuel to the rail. I did not change out the hard line that connects to the from the difp to the fuel rail. Worst case scenario is debris made it past the old pump into the fuel rail & clogging injector filters.

While i was e-tuning I did a WOT data log for Drob from 2k rpm and as soon as I hit 4k rpm the car went into limp mode and gave me this code. The lpfp that I upgraded to popped out inside the basket and one of the o-rings ended up getting ripped which led the fuel to seap out from around the o-ring and caused low pressure to the hpfp. I know it’s a bit different from your situation but low pressure can be caused from the lpfp.

I get it, fuel problems are a PITA. If you tackle the the lpfp your going to need a adjustable lock ring tool to get to it easily….trust.
