Kevin,
There are not many options to raise the idle on a 03. While studing the manual and drinking more than a few beers I came across what I thought might help. The power steering pump has a pressure sensor switch that is normally closed. When the PCM senses high pressure such as when parking, it raises the idle to compensate for the load. The window switch opens the sensor circuit signaling the PCM to raise the idle. When the engine reaches 1000 rpm it returns the signal to normal condition. When the engine drops below 1000 rpm it opens the switch and the idle holds at 800 rpm and slowly slides down to about 675 rpm. I think this will make a cam normally not suitable for a 03 tunable.
