Big load and truck runs better

[Diesel Freak]

I helped my Dad haul an old Ford 4600 tractor today. I guess all the short trips and grocery runs have carboned up the combustion chambers a bit. Well after grossing out at 17000 pounds and going over 100 miles with sustained EGT over 900F for a few miles my baby is running like a raped ape Wow does that Cummins like to work! Now throttle response is perfect and it seems that all turbo lag has dissapeared. I can't wait for haying season now... . then I can really work my baby.

Hey Morph Head, I just have one question. WHEN are you going to move out of your Mamas house . LOL. I'M BACK.

Well I will move out of "my Mom's" house as soon as your mom stops paying the "rent" at my curent place. if you know what I mean?

She is paying yours to?? lol

You might be feeling the classic ain't got a trailer on the back no more syndrome. Loaded your truck is big heavy and slow right?? Well the truck will naturaly feel like its gonna haul after you take all that wieght off of it. It also goes along with the "ain't been driven in awhile syndrome" I like this one because if I don't drive my car for a month or two it seems %100 faster than it did when i put it in the garage just my . 02

I have noticed the same thing and it is not no-trailer syndrome. It flat runs better after working it hard. I wonder if it something that the ECM "learns" when you are just putting around empty? In a couple hundred miles it will be back to its' old self, till the next load anyway.

There might be something to it...

I believe there was a thread where Marco stated the software of the ECM can and does learn driving habits. This may be why the owner's manual states that it is good to work the truck hard during the first 6000 miles.
