Default MAF and O2 problem

I put in a 383 build. Motor only has about 1700 miles on motor. Haven't taken it back yet for the final tune. So it is still on the break-in tune. I every so often keep getting a MAF code and O2 sensor code. I replaced the MAF sensor with one from Advance Auto. The O2 sensor was replaced when the new motor was put in. I can clear the codes out and the SES light won't come back on for a while. I can drive it for a couple hundred miles or more and the light never comes on. But today it came on out of the blue. so I've gotta get it cleared again and ready for inspection. It has 60lb injectors in it. So I know its probably a little rich. But the tuner knew what was in it when he put the break-in tune on it.

Just can't figure out why these damn codes keep popping up. It shows "high output circuit" for the MAF code. Whatever that means. Any advice or ideas what to look for? Thanks.
