P0171 after install?

[Thrasher2019RS]

Good morning ya'll,

I'm in a 2019 Sonic RS Hatch, with a few ZZP parts installed already (CAI, coil pack, catback 2.5" exhaust, few minor things otherwise).

I wanted to get ahead of the looming PCV failure and engine death, so I got the ZZP PCV bypass kit, and I installed it this weekend.
AT THE SAME TIME, I installed their wastegate actuator on my turbo assembly, since I was in there.
I followed instructions completely, backtracked several times from my own idiocy, but got it done and correctly installed.
Car started and even runs fine, but I threw two codes this morning.
P0234 is the Turbo overboost, I know that's a thing, I'm ordering a tune asap.
Second was a P0171, Engine lean mix code.
This one's got me intrigued, because a wastegate actuator swap should not cause that, and I know the PCV bypass doesn't alter that either.
BUT the one thing I didn't like during reassembly was when I went to put the fuel rail back on, I got the feeling the injectors didn't seat properly, like a "snap in" feeling as a slid them home, though they seated far enough to allow me to bolt the rail back on with no forcing or pressure at the screws.

Anyone got a clue?

I can always uninstall the wastegate actuator, that's actually pretty easy, to see if it all clears, but haven't had time yet.

Thanks,
JOSH

Just something to think about. I had an issue with the same codes and found that my intercooler outlet charging was cracked. It was a real head scratcher but when it found it, it made so much sense. I’d check to see if that’s the case, do you have the factory intercooler set up?

Yeah, factory still.
I'd like to do the ZZP intercooler upgrade package soon, but since the wastegate upgrade requires a tune, I'ma just uninstall for now (ordered a new OEM version) and then do a reset.
