Zero dark

tuned with uprev but switched from k&n to takeda cai about 3 weeks ago and 2 codes popped up resulting in lean codes.

Is it safe to drive? I would assume it isn't too lean but enough to throw a code off. Waiting a couple weeks for exhaust to be finished before getting a new tune which is when I will be able to solve the problem.

Also have berk hfc
