So I've been struggling with this issue for a while now. Bank 1 just shuts down and trims flatline. No codes are thrown. After, I've seen super knock shadow codes for cyls 1-3. It seems to happen more at higher boost / rpm, but no issues triggering it even at just 20psi. Sometimes it will even recover mid-pull.
I've replaced injectors (high and low pressure), hpfp, o2 sensors (bosch adv), 2 step colder plugs, swapped injectors, plugs, and coils between banks, and a handful of other attempts to get to the bottom of this. Nothing works and I'm at my wits end. It always just kills bank 1.
Mods are in sig..
Here's an example where trims flatline and it kills bank 1:
And another where it does it and recovers mid pull:
