Diablosport Forums

I recently purchased a 2002 F-350 Powerstroke (bone stock.) I have added a S&B cold air intake a Diablo Sport Tuner (using economy tune) and I cut the muffler off. Now when I gas on it hard the engine light comes on. Anybody had this problem or does anyone have a solution. The Diablo realy made a difference in power.

The codes I got are.
P0603 Internal Control Module KAM Error
PO541 Manifold Intake Air Heater

What does that mean
