Hey y'all, been losing my mind over this cylinder 6 misfire. Speedtech 6266, stage 3 lpfp, index 12 injectors, ngk 95770 0.22, 91 octane.

Spark plugs have a few thousand miles on them. My injectors have almost 25k miles so maybe leaky injector? Here's a log on wastegate pressure, tried to go past 5k rpm but it was misfiring so bad I let off.

Pulled cylinder 6 spark plug to check for fuel or oil. No signs of either on spark plug. Swapped in an extra spark plug I had and switched ignition coil to see if it moved cylinders. Still misfire cylinder 6. Did another log afterwards. I noticed at around 4400 rpm hpfp crashes and cylinder 6 shuts off causing bank 2 to go lean. Does this point towards hpfp failure?
