93 Octane

2nd Pull last night

3 and 4 gear logs

Zero to 50 mph hard pull, with no-lift-shift, Map 1, 535i, Stage 1

The "new" HPFP used in the run on 10/2/22 was a remanufactured unit which failed a couple days later. I replaced it with a new OEM pump from the dealer today and these are the first 2 pulls on it. It's marginally better than before, remaining just over 1000 psi. AFRs don't look like they're going lean, so is this ok? Can you see fuel injector duty cycle? I wonder if that will tell a more complete story. As noted in the last log, the boost leak was found and corrected. There are still several big hesitations as the engine pulls through the revs range.
