Default What is wrong with my logs

I have a 2003 5mt WRX hatch that I got from a charity auction and fixed it up and now that it works I am looking to tune it correctly as it has aftermarket K&N short ram air intake. As my title shows I am a noob but I have read a lot of things on this forum and ROMraiders forum that suggest that my AFR at any given time should be 11-14 but I did a pull from stop to around 5k rpms in 2nd gear and my AFR started around 14 and went up from there into around 21. Everywhere I look says my car should have blown up by now and I only throw lean codes if I am on the freeway. Do I have a broken sensor or something or some other aftermarket part I somehow missed I just feel like this can't actually be the correct numbers with only an air intake. Also note I live in Salt Lake City which sits at about 4200-5000ft above sea level and the car was at sea level for most of its life before me.

Is there a reason no one is answering? Did I do something wrong or not include something I really want my car to not blow up. Do I need a wideband? Is my tactrix 2.0 cable broken? I cannot flash the ECU either please I need help.

You probably need a new o2 sensor or something. If you were running that lean then you would have almost definitely had some more feedback knock.
