?Hello world. I have a 04 6.0 crew cab 4x4 and I've lost power on my way home a few weeks ago. It'll crank up and idle fine but it won't go over 1800RPM without feathering the pedal. It won't rev if you stomp on it, you gotta eaaaase into it. The turbo still spools down and sounds like it should. Now, like many other 6.0 owners I've researched and tried the inexpensive options first. All the turbo connections/rubber hoses are new no cracks/leaks. I tried a new ICP sensor. No change. New intake sensor. Stuck a coat hanger down the breather hole for the MAF sensor on the valve cover, and replaced the 1/4" rubber hose. New IPR. Nothing changed. I changed the fuel filters, changed the oil, added some RevX. Still same symptoms. Tried reprogramming back to stock tune, tested FICM (48v) I'm lost...The truck has 175# injectors, 72mm turbo, blue spring kit, EGR delete, Studs, cold air intake, 4" exhaust to a bed stack, SCT with Looney Tune, So this leads me to think I'm looking at replacing the HPOP next. Possibly with a Terminator 500 or Adrenaline? I'm not sure. It's a late 04 engine with the ICP on passenger side valve cover. Any input would be appreciated. What do I need to buy next?
