Check the iat sensor on the bottom of the cold side pipe and make sure it's plugged in.
You didn't by chance install a 5" cold air intake at the same time didn't you? If you did, you need to get the maf rescaled in the tunes.
If you didn't get your tunes modified, you are eventually going to get the P132D and P007E codes as well. Get your tuner to shut those off.
Its common to get the high intake air temp one after a larger turbo as they move more hot air than the older turbos.
