AP v2 CEL HELP

Hey guys, i just flashed to stage 1 today and after driving it for about 30 minutes (some aggressively, some normal) i got a P0171 code for running too lean (bank 1.) I stopped to tighten my BOV pretty much all the way closed (venting less air outside) and drove home about 5 minutes later with the light still on.
When driving normally, my A/F ratio was low 14s/high 13s and when driving more aggressively it was going from 14-21. I'm not sure where it is should be. Also, my boost looked pretty much where it should have been.

What can i do about this?

thanks

BOV shouldn't be a problem now that its closed, i think its my cai. Thats what most people who have had the same problem have said. I'll just switch it out for the stock intake.

That would have been great if that was mentioned earlier. Both the BOV and the CAI arent even an upgrade for a WRX.

+eleventy billion! The stock intake with a modified snorkus is the only intake mod you need unless you decide to go to a FMIC. Same goes for the stock BPV. PUT IT BACK ON. Also, clean your MAF with some CRC Electrical cleaner and reset your ecu. Problem solved.

I dont have either, but will get a stock intake and keep the bov closed until i get a protune. Then i may put the cai back on and open the bov if i want to. The tune will allow those without problems.

The tune would probably help with the CAI, but not the BOV. You cant tune for one of those.
