I put my new Diablo Revolution dual program chip in yesterday. It really woke the truck up compared to the Superchips I had in there, and best of all no more detonation. But when I turned the truck on the second time, the SES light was on. Took it to AutoZone, and code P0103 came up - Mass Air Flow Circuit High Input. What does this means, and how might I fix it. I guess I should talk to the tuner first. I'm going to take my MAF off and clean the sensor with some contact cleaner to see if that works.

Any ideas?!?!?
