lacking power

I have an 03 F350 w/6.0 liter. When I first start it and try and take off, it has no get up and go. I usually baby it until it warms up, but even if I have to get on it, it won't go. I can put the throttle to the floor and it just slowly takes off. Usually after a few miles it seems pretty good. I've had the problem for years and have just gotten used to it. But, I changed my oil this weekend and now its even worse. Any ideas what could be wrong?

one of a few things.
could be ficm.
charging system voltage
low fuel pressure.
low icp
or bad fuel injectors.
I suspect fuel injector issues.

I vote ficm. Mine is bad and it runs like crap when it's cold. Going to re-run the solder, but I'm waiting until I have a thousand bucks to replace it when I screw it up. :-)

It's my first diesel and I've had it for about 6 years. Its been good except for this problem. I've never heard anything good about the early 6.0's. Whats ficm? I've been told to clean the EGR but a little leary about messing w/ anything on these engines.
