According to my book they are all the same...

5.9L (360") 6-Cyl. Turbo Diesel 24-Valve & High Output EFI

AIH, TWC, CB, MIL, AIH-TS, CB-VC

AIH Air Intake Heaters

TWC Three-Way Catalytic Converter

CB Crankcase Breather

MIL Malfunction Indicator Light

AIH-TS AIH Temperature Sensor

CB-VC CB Vapor Canister

I do know for the 2002 there is over 44 different ECM produced for my truck so its really possible the software is the biggest issue!

Assuming you have an early 04. Your Cali model is physically identical to the SO model, with the only difference between SO and HO being the style of piston cooler.I don't know about other programmers, but a Smarty or Smarty Jr will make your truck an HO, then add the tune on top of that. So on SW3 on a Jr you are really getting about 170+ hp (70 at the flywheel, and 100 at the ground).

The 04.5+ trucks are all 50 state legal. The '03 and early '04 trucks could have had Commyfornication specs from the factory. The regular '03 and early '04's were rated at 305HP and 555ft. lbs. The Kalifornia specs were 235HP and 460ft. lbs. I believe.

The 305/555 specs were HO, there was also a SO in 03-04 at 250/460.
