... Elias, I was replying to the guy with the low MPG. I think any of the Big Three ought not to bite the hand that helped make thses big American pickups so popular. IE, having the CPU record any mods. The aftermarket has become quite sophisticated. Sure they might catch a few idiots, but many buy these trucks with some modedrate moidifications in mind, and it has improved the breed and market share.

i hear ya roland. i admire diesel trucks, and am trying to think of an excuse to buy one. unfortunately i don't have anything to tow and am not likely to get a boat or track-car or airstream... if diesel cars with stickshift disappear frmo the marketplace, maybe then i'll consider a stickshift diesel truck since presumably those will remain available 'forever'.
on the way to work one morning i met a local dude getting coffee too. he was driving a recent diesel GM pickup and had left it running in the parking lot. i commented "nice truck, i'm going to go steal it now since you left it running". but it was running via 'valet key' and he had locked it remotely. awww!
then he saw my GTO and we talked for a while over coffee - i think he's the president of local BMWCCA chapter, which he invited me to join. he uses his GM pickup to tow his "track car, a modded M3". later as he accelerated onto the highway i was quite impressed by his pickup's pickup! and soot! 
(this was before ULSD, so his exhaust was sootier than it would be today.)

... One of the major parameters, in a sophisticated, fuel map is to not add fuel until the turbo can supply enough boost to burn it properly; however this does not appeal to our heavy footed youth. Hence some of the reason (?) for soot on acceleration.

The route I often take on a bicycle group ride out in the developing country turning to suburbs includes a section of two-lane road over rolling hills with no paved shoulder. Even though we get as far to the right as we can, a vehicle sometimes cannot pass right away.
This irritates some mostly young men and when they do pass some of them really lay into the fuel in their diesel pickups, and pour out a cloud of soot right into the cyclists face.

Has anyone found a minimum 45 cetane fuel that is required by Ford? The only fuel I can find (in Virginia) is 40 cetane, and add a cetane booster when filling up. Any suggestions?

I am looking at twi '05 F250 crew, 8' bed, Lariat trucks. One has a chip and claims 17/22 mpg (65,000 miles) the other 10 city/ 13 hwy (45,000 miles). Since there is only $2,000.00 difference in price yet both trucks basically identical which should I lean towards buying? Pros and Cons on chips is the question.

I just made a round trip trip to Mississippi from virginia with my 2008 F-450 pulling a 14,000 lb fifth wheel. At 65 MPH with a 20 MPH head wind, 6.8 MPG's. No wind at 60 MPH i averaged right around 8 MPG. When I slowed down to 55, I got 9.6 MPG. As you know this is minimal hills. My MPG was worse when I went into tow mode. I took a trip to DC one day and got 10MPG not pulling at 65 MPG. This truck has the worse MPG I have ever seen. I blame EPA vice Ford because of the new diesel requirements, restricted exchaust etc.... Great for pulling, forget I have anything behind me.

I have a 2000 F250 with the 7.3 liter Powerstroke. I get on average 15-16 MPG all the time. Made a trip from Oregon to Pennsylvania towing a 31 ft travel trailer, maintained 65 MPH all the time and averaged 10 MPG for the entire trip. This truck is completely stock, no chips. The engine now has 134000 miles and it outperforms most of the newer diesels.

Wow that sucks!! I know now that I really dont want an 08. I was doing very well with mine at first besting 21 mpg empty empty. tailgate down. 60 mph. Now at 60000 miles on my '06 6.0Ltr I average 16-17 mpg with about 1200 lbs in the box and almost as much inside. so not light at all. When I tow its around 20000 lb GCVW 5th wheel and Truck with family and gear. I get 10-11 mpg. This is with 5" exhaust turbo back, and s&b air filter. no chip or programmer. You can now get after market exhaust for your truck!! you need it!! and a S&B air box.( its the only one that passes the Ford iso test) try those and see what happens. you should put your truck and trailer loaded on scales and see what the weights are. I was about 5000 Lbs under on my initial guess. Maybe you can cut some things out to save weight. and keep your foot off the pedal. I know those trucks are fun to drive and have lots of power. other than the milage how do you like it?

6.0 and different programmers and chips

What have you guys (and gals) tried and liked or disliked for the 6.0 Ltr?
I have tried the triple pup and almost killed my torque convertor. Every person I have talked to have said the triple pup is hard on tranny's.
What do you people recommend as far as programmers and chips go?
