2003 7.3 wont rev past 2500 rpm

driving the truck on highway or wherever and if you need to pass a car and get on it it wont rev past about 2700 rpm. no power on top end.. any one had this problem? does it all the time

hey, i doubt this helps you much but my friends had that problem when put a new turbo wheel in and didnt get it seated, the truck wouldnt build enough boost because the wheel had to much drag on the housing of the turbo. tightened the wheel and problem solved but i would think it would be a large amount of play to get that kind of issue

I'm assuming you're talking about a max of 2,700 at WOT. Did it just start doing this, or has it always done it? Any smoke while it does this?

Check the oil. If the oil level is good, try to get ICP #s and duty cycle. Sounds like a HPOP problem. Wouldn't hurt to check for boost leaks.

Fuel filter?

Fuel filter, fuel pump, or hpop. those are what I would check.

Yup, start small. Start free.... Look for boost leaks. No leaks move to a filter. And on.
