Test Run #1, 2k-7krpm, no DTC Installed PR Stage 2.5 bucketed performance pump.
Threw 29D2 - misfire cyl 6, 2C7B - O2 sensor after cat, 2DED - power management closed circuit violation, shadow 2AAF - fuel pump plausibility.
The shadow code may be from the new low pressure fuel pump voltage threshold.
I will replace the O2 sensor, and may switch to PR B58 coils from BL R8.
