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?
