This is lean as while you are in low boost. Several times I saw pretty decent amount of boost while the narrowbands report higher than 14.7 and several times still looked like it wasn't in PE.
I didn't see a wideband on any logs. I must have missed it.
The fuel pressure variation is coming from the AUX pump. Those kits are garbage. I'm sorry to say. They are especially bad on manual cars. I refuse to work on cars with them anymore in our shop.
The issue is the aux pump comes on.. fuel pressure spikes high. (note a lot of injectors stop operating around 85-90 psi) so you get injector misfires that way. The FPCM rolls back the main pump with short and long term fuel pump trims, then when the aux pump shuts off the pressure isn't there because the FPCM saw it high moments before. So you get this 90 psi to 35psi variation while rowing the gears.
So..
1. Make sure you get into PE with any boost. If its still lean in those spots, well that is just tuning 101. Enrich the maf or VE in that spot.
2. Be conscious of that fuel pressure swing and realize it is going to cause driveablity issues on its on.
I don't see P2V issues being a issue here. Any built motor is going to have pretty significant valve reliefs. It's next to impossible to find aftermarket piston without valve reliefs.
