Ok I've been looking into a newer truck. I found a F350 that is already set up the way I would like it. I have heard many different stories about the 6.4's. So if anyone has one can you give me your thoughts on it. The way I understand it, if they had a programmer, or a chip on them.....Walk away from them, is this true?

Thanks

Jason

A programmer or a chip means they have turned them up to run beyond the factory specs, which usually shortens the life.

The worst thing I've heard is that they are thirsty. A chip or program ain't necessarily an engine killer. Depends on how it's been treated. Some guys chip em and use them as necessary with good maintenance. Some take em to the drag strip and beat the wheels off of em. Try to get a feel for the seller.

The 6.4 is a hot rod when tuned! Delete the dpf and get a tuner that will support that mod. Fuel economy will go up greatly with those mods. Yes it will cost about a grand but if you plan on keeping it awhile it will pay off in the long run. Look for milage to go from 10ish upto 16-18ish depending on driving style. I wouldn't expect a 6.4 to go a million miles like a 7.3 but 400-500k would be a reasonable expectation. Also block off or delete the egr coolers. The egr cooler is not as big of a problem on the 6.4 as it was on the 6.0 but I'm still leary of them on anything!

This is my opinion fords make a good platform for a cummins. I have an 85 F250 with an engine out of a 93 dodge and I get 22 mpg on the freeway. My plan is to convert a superduty and have a really nice truck.

I just talked to a guy at work today that has a 2009. He has done everything you just said. An has had the same results you talked about. He is VERY happy with his choose of truck. He was a Dodge/Cummins guy for a long time too. He said with the mod's he has do it runs like a beast. Thanks

I've been a Ford guy most of my life, but if I were in the market for a diesel P/U I think I'd buy a DuraMax - smooth, quiet, powerful, relatively reliable and efficient.
Yes, I'd prefer a Cummins, but there is no way I'd own another Chrystler product, a great engine is useless when the rest of the vehicle is falling apart around it.
As to the PowerStrokes - until this most recent Ford built one that hasn't been out long enough to prove anything good or bad, there hasn't been much good to say since the 7.3, and then you're talking about a 10+ year old truck.
With current fuel prices, if a 6.4 is only going to get 10 to 14 MPG, myself, I think I'd buy a gasser of some sort that will get 7 to 12 - the entry price will be lower & the maintenance is much cheaper. The diesels are fun, and if pulling trailers 75% of the time, are the only way to go, but $50 oil changes and $3000 for a set of injectors make it hard to justify in my mind.
