P0506 - Idle Control System RPM Lower Than Expected

When you installed the intake did you unhook the battery?

I had the same problem, I've got similar mods. I replaced the TPS and problem went away.

If the truck is running somewhat fine I would unhook the battery for about five minutes. What this does is it resets the computer and it will re learn (will also reset the code). Once you put a different intake on the airflow into the engine will be different, which is why you want to reset it to re learn the new airflow. Give that a try then drive it around regular and see if the light comes back on. If it does then we will check something else. Always start out with the cheapest fix first especially the free ones.
