Okay gurus, I was checking codes on my truck and found this; "P0603 Internal Control Module KAM Error". Is this a code that pops up after clearing all DTC's like the 1000 code or is this an issue I should have looked at? I just had the PCM replaced along with a lot of other parts and flashes. Seems that Ford is changes programming almost as fast as I change my underwear, LOL.

sorry matt not trying to cut you but this code is not to be ignored, not on a 03. waterboy, if you are running a tuner go get it updated. a p0603 will affect your ac performance by cutting the compressor off at odd times, it will affect oyur shift points, and it will never let the vgt learn cycle run long enough to make full power out of this truck. your best bet is get this code out of your truck because otherwise, poor fuel mileage and low power will result.
