2006 F-450 6.0 5 Speed auto

Hello, I have a 2006 F-450 4x4 Crew Cab with the 6.0 in front of an Automatic, with 4:30 gears.

The only mods are 4" exhaust, and a Double over Gear Vender Transmission.

I haul/tow heavy loads between 35,000 and 45,000 Gross.


The pickup has 180,000 miles on it, and installed 1 EGR cooler, oil cooler, and 3 EGR valves. Now I'm having trouble making power off idle, like when starting loaded. I have been told by several mech. not to chip the 6.0. What do you guys think the problem is?

Has the turbo ever been cleaned/serviced? Sounds like the vanes may be sticking.

You don't "chip" a 6.0, you reprogram it with a tuner like a SCT, best results are with custom tunes from one of the many venders that write custom tunes.

But as for the heavy towing that you are doing ... it's probably best to stay with stock power levels, but you could still use a tuner with a custom heavy tow program that tunes the trans for better shifting but keeps the stock engine program.

Do you have any gauges to give you some engine data during the "low power" condition? More info will definitely help us help you. The turbo vanes will stick when the truck sits for extended periods of time. I make it a point to run mine wide open at least once a week to make sure everything is cycling correctly.

No it is stock. I pull a lot, so I don't think it is sticking. It is having a hard time getting spooled up, I think.

Any soot on the firewall? The bellows inside the up pipe expansion joint can crack. This exhaust leak will rob the turbo of needed flow. Check you turbo connection boots for any cracks or leakage. Clean the carbon out of the exhaust back pressure sensor tube. Remove the EGR valve and clean it out ( could be sticking open) A lot of 6.0 EGR valves are NOT bad they only needed cleaned as they soot up and stick open. I highly recomed that you get an engine monitoring solution such as a scangauge2 so you KNOW whats going on inside your engine. See the t-shooting guide in my sig for more info.

What are you towing that is so heavy?

As Ham said, without something like the ScanGaugeII, you will be guessing for an answer and/or throwing parts at the truck. The $150 investment will more than pay for itself when you are able to diagnose and the repair are without taking it to the dealer.

I bought mine on ebay. Use google and you may be able to find retailers offering it for less. The unit is relatively small and can be mounted with the included velcro tape.
