Anybody here have any experience w/ Ford SD 6.0 PSD?

Yea- me too Builder. I plan to keep mine stock until the 5yr/100K is up, then it might get modified in the form of a program or chip.

I just have a tough time wrapping my brain around this: someone has a 500+ HP 6L that races other cars & trucks at stoplights and frequently tows a 15,600lb trailer getting 4-5 more MPG than a stock, gently driven 6L.

I have trouble too as far as the mileage is concerned. It just doesn't make sense that you can jump the motor 200hp and gain that much mpg. Even to just change exhaust pipes or intakes or any of the other simple mods people say they do to gain a hp increase doesn't make sense to me. With the government cracking down on the OEMs to improve MPG then if all Ford, Dodge or GM had to do is put a bigger exhaust on their trucks or change the intake then it seems like a no brainer for them to do it straight from the factory. There has to either be more to it as far as a negative which is why the OEM's don't do these "mods" as stock items if they are so great for mileage. That or it is a case where people who do these mods skew the numbers to convince themselves it is money well spent. I am not accusing anyone but it just doesn't make any sense if it is as easy as some on here say it is to gain 5 mpg.

I guess short of buying all these items and modifying my truck personally and recording each items effect on mileage then I have no way of knowing for sure. Most of the times I have seen these mods reviewed it is to review the hp gain they give the trucks. So if anyone wants to start donating money for me to use my truck as a test mule with some of these mods please let me know and I will give you my address for you to send the checks

Deereguy,

I guess we have to tell these guys that the best kept secret about the GM HD's is how fast and strong they are stock.

I don't need any power modifications. I did spend thousands putting them on every Ford Superduty I ever owned because I was always behind on power to GM & Dodge.

I don't have to do that now.

That's exactly right. It's hard to believe in an age of when car manufacturers have to carry 40MPG econoboxes at a loss in profit just so they meet the CARB, CAFE & EPA standards so they can sell fuel guzzlers that they wouldn't supply these chips, intakes and exhausts on them.

If diesel truck engine engineers like Clessie Cummins were alive today and he could put a "chip" in an engine that would make it get 4-5 more MPG and nearly double the HP, they would. The reason they don't is because double the HP causes accelerated breakdown of drivetrain components and premature failure which means increased warranty claims and ends in higher truck prices for all of us.

Even if a "chip" just improved fuel economy alone, the manufacturers would just add their programming into the vehicles PCM, but they don't.

Why?

I haven't drove my friends duramax much but it was a nice truck and power wise it seems about the same as my 6.0. I have used it to pull a few trailers and they are nice trucks but I don't see one truck being vastly superior to the other performance wise. I know you are joking around and it is fun to rib people about their trucks at times because some people take their trucks way too seriously. The more seriously they defend their truck the more fun it is.

Of course! What's the matter with a little friendly competition???

You're right, no truck is vastly superior to the other. I think Ford is superior right now to GM in GVWR, but I think GM is superior to Ford in powertrain. It evens them out and makes them highly competitive. If Dodge could get their act together, they might just make the best truck of all 3.

I don't tow 15,600lb boats all day long like D-pilot. I pull a 12K equipment trailer a few times/month, so I don't need as much towing capacity. I value powertrain over payload, so GM suits me better.

All in good fun!!! Flame away! I can take it!

Like I said I can make it get 10 mpg or 23.6 mpg. Of course if I take it to the track and run it or if I am playing with it at every stop light it kills the mpg. I mentioned this before. Believe what you want but I know many guys getting 20 plus mpg with 1 ton diesel trucks of all brands. I also know guys who do like you and get 14 mpg or less. Its all in how you drive it or what you do. I would guess if I took every mile I have driven and factored in every gallon I have put in the tank it works out to around 15 mpg. All I am saying is if I watch how I drive it I can get 17 city and 24 (23.6) highway. Heck if I wanted to get 10 mpg I would have keep my Hemi or got the Fords with the V-10 gas motor.

Just cause it has 500+ Hp does not mean you have to use it all the time. If I am just driving it around doing daily driving or going on a trip I keep the RPM below 1,900 and try to keep it at 1,900 with the cruise on while driving. This yields the best economy in my trucks.

Why?

You answered your own question. Does not matter if its a Chevy 350 or a modern diesel engine, you do something to increase HP it is going to make the engine less reliable due to increased stress. I know this and can live with the risk. As for the simple things like chips, intakes, and exhaust if you read the literature that comes with many they are not approved for many aplications so that makes them non street legal. My state does not have emissions test so I am not sure of the negative impact of them.

Take the 86 Ford Escort I had. It was a 35 mpg car. So why is it now days all the manufactures brag when they can make a car 20 years later that gets 30 mpg, they should be getting 45 mpg? Remember how simple these engines and cars were? No real smog equipment, no power steering, no air bags, no power locks and windows, and they were light weight death traps. The manufactures have made great strides in engine efficiency but due to new regulations we are not seeing a increase in mpg. Same thing happened last year with the new diesels, I am sure this is why you got a pre dpf engine. Seems stupid to me that yes you are making the air cleaner but you are using 40% more fuel to do so.

Actually, I only answered part of my own question.

I also stated that if installing a "chip" would increase fuel economy (as you imply it does) then all manufacturers would install the part of the chip programming that improves fuel economy.

BTW: If you removed your cat converter when you did your exhaust, you are violating federal pollution standards.

OK now I'm scared. I just bought a new 08 F250 6.4 to tow my horses around. I read a lot of reviews that stated the reliability at 10 out of ten.
The deal I got on it seemed to good to be true. Hope that is not the case.
I have less than 500 miles on mine so far but love it. I took my new truck to Cabela's last week (about 50 miles) and watched it go between 18-20 mpg.

I have owned a lot of Fords over the years an with the exception of the areostar lemon that I bought when I was young they have all been real good to me.
