2005 6.0 Bad acceleration

We recently bought this truck and it only has 81k miles. It starts and idles fine does not smoke white or black smoke and it has trouble getting up to speed once it gets passed like 40 mph. Ive read a lot of these forums with similar problems but most of them had smoke problems or some other thing that mine isn't doing. The truck runs great it just feels like it has no power once you smash the gas pedal. Anyone had this problem ? Like I said it runs and starts great and doesn't smoke it just doesn't want to accelerate at high speeds. Need Help Please!

I forgot to mention it also has a Water In Fuel signal on the dash. The truck is all stock but its supposed to have the EGR delete already installed.

I would start by draining your water seperator and changing both fuel filters if you haven't already.

Ok will try it. When we bought the truck it was a wreck slight damage to hood and headlights no serious damage the people fixed it and it sat a while im sure. I was reading and i think it could be the fuel pressure. On the stock gauge we are building low boost something lik 8 psi its hard to read. I know mechanics somewhat but im new to diesel. Thanks for the help

Change them fuel filters!

If you have a "water in fuel" read out, change the filters before you eat the injectors! The dealer can also add a lever kit to the water separator so you can service it more easily.
