Yes, that is not terribly uncommon. You are getting more air, faster, to the engine so it could cause the lean reading. I am sure someone here will be able to tell you how to help correct that problem.
Welcome and good luck!

You need to get a tuner. The CAI is messing up the MAF readings and the computer is freaking out. A tuner can re-set the MAF curve so you can run the CAI with no problem. You need to get an X-cal2. They Hyper junk ones will not work.
