Need help diagnosing benchy problems (imgur.com)

I finally got my printer working again. I spent the whole day going through Teaching Tech's calibration steps. All the flat calibration gcode looks fine. The Benchies are another problem though. I'm printing with a 0.6mm nozzle for the first time.

On the smaller benchy I printed at 0.2 layer height, with a perimeter speed of 40mm/s at 210/60 temps. The bigger one is 110% larger and printed at 0.25 layer height, with a perimeter speed of 60mm/s at 215/60 C.

The problems are mostly manifested in the same area. Big blobs in the rear and layer shifting on the tail pipe. Large layer shifts/bulges in the center. I've never really ran into this problem before so I don't know where to start when diagnosing this.

I skipped those. It's Atomic filament, and it's the only brand I've ever used. It's just a different color. So I've been using the same temps as I used before. When I did the Slicer flow calibration test, it gave me the cleanest test prints I've ever had, so I figured it's not actually that different from a 0.4 nozzle and skipped the temp, speed and flow, and retraction tests. I went straight to Acceleration tuning and again go the cleanest test prints this printer ever put out. Then the benchy shit the bed. I'm gonna spend the day doing those three tests I skipped.
