CEL codes being thrown

so i just got my tuner and CAI and installed them tonight and thought to myself why not put some 91 octane in and have some fun. so i did and was having a blast. then i went up to sacramento (which is about 25miles~) and on the way home i saw that i had the CEL on. so i got home and plugged in my tuner to see what the codes were and they were P0174 and P0175 for being too rich in bank 1 and bank 2.

so i am wondering what could be causing this?

The MAF sensor may be loose/installed improperly/missing its gasket/contaminated with oil from the air filter, or there may be a vacuum leak downstream of the MAF sensor(loose CAI connections, PCV hose not installed or installed improperly).

^ This. Double-check all your connections, I'd bet something came loose during the drive.
