Default P0108? What causes it. Noob needs insight

Hello all. On the way home while getting off the freeway my car went into R.E.P mode I was able to get home and get the code. The only current code was P0108 I reset it and drove the car around (town/freeway) to see if it would comeback and it didnt. I wanted to know what causes it. Also if it helps the car doesnt idle rough and it started right back up. Car is a 99 a4 with 131k miles with a kn intake, a ported tb(shaner) and a pcm tune from ecs. Thanks to all who respond

1st thing you should do is bookmark this webpage;
http://www.stengel.net/diccodes.htm.
P0108 Manifold Pressure (MAP) Sensor Circuit High Voltage. I can't tell you what that means but I'm sure someone else can, good luck.
