That is not a lot to go on. Right off I would be checking the two main things needed. Unrestricted fuel supply and unrestricted air flow.

Check filtering of fuel and filtering of air. Are the filters changed on a regular basis?

How many miles on the truck, how long have you owned it what have you repaired or replaced on it. Have you done any major modifications? Etc.

Is there any way to check fuel pressure (and or flow?).

My 2001 7.3 Turbo is pretty stock. I am sorry, I don't know much about chip packages.

If there is anyway you can ask the previous owner about this? -- that is where I would start.

By the way there is a lot of help on the internet. Lots of You Tube stuff and the like. I learned a lot from forums like this and from research. It takes time but it also saves you thousands of dollars over having to take it to a garage --- they love to see a diesel come in because they can overcharge you at will!

Wish I could be more help. But do the research and be patient.

If the fuel pressure is low, you then can diagnose the fuel pressure pump, the fuel lines, and the fuel tank for probable causes.

Good luck God bless America!

The main purpose of a powerstroke intercooler is to cool the turbocharger compressor discharge air. Front-mount intercoolers are typically installed behind your vehicle's grille, and it routes the discharge air through a high-efficiency heat exchanger core. This allows for a lower exhaust temperature as well as an extended engine life for your vehicle. These units are typically designed to fit specific vehicles, but a universal intercooler is designed to work with many different vehicle makes and models. Universal kits can include aluminum pipes, silicone hoses, and stainless steel clamps required for a complete installation. Sizes vary, but many intercoolers measure around 28 inches by 6 inches by 2.5 inches to easily fit behind your vehicle's grille. A powerstroke intercooler allows for better fuel efficiency and increased power. With the large inventory on eBay, you can find the right size unit for your vehicle.

I would expect the turbo to get hot, with the exhaust gasses routed through it. How hot? Glowing red hot? Do you hear metallic squeaks coming from it? Can you hear it spool up?

You may have a boost leak. Not knowing much of the history of the truck, you are going to need to do some serious diagnostics. It is difficult to postulate with the amount of info you have. Is there a reputable diesel shop near you that would be willing to do a diagnostic? Maybe if you post your location someone in the brotherhood here that has the right scan tool may be close and willing to help for a six pack or two.
