Duramax owner thinking to swap to 6.4

[Lccountryboy89]

ok so I currently have an 04 Silverado with the Duramax, EFI Live, PPE tranny and all that good stuff. She just rolled 116k miles and never given me a single problem. It's an extended cab and I really want a crew cab (and bigger interior that the 250 has). But after reading some posts on here i'm scared to death to pull the trigger on this deal I found... it's an 08 F-250 King Ranch with 80,000 miles on it. It's a job one truck (built 6/07). Was a fleet vehicle that was serviced every 3-5k miles. Ran the Oasis and looked good. Had radiator replaced at 39k miles (2009 I believe). Also paid $85 and had the Ford technician look over it. He found no problems... should I be concerned about this truck or go ahead and go it. I can get that truck for pretty much 10k out of pocket plus my truck. Any input???

get it, delete it, drive it, and love it

As long as it was maintained and feels tight. Have at it. I would assume the go fast treatment would be in the works. If not, seriously consider it.

oh yeah that'd be the first thing I'd do. I already talked to Charles at KEM Performance and he would hook me up with the DPF delete, S&B Intake, H&S MiniMax, and 7KEM Custom tunes. It still has the DPF right now but has a Bully Dog GT on it. Should I be worried about it going thru regen for 80k miles? Would this affect longevity? Are there lots of 6.4's with over 100k miles on em??

There are quite a few, you may have to have the pcm reflashed from the bullydog. I don't remember where I heard that though. The sooner that imodium pill on steroids comes off the better. As the truck regens, fuel makes its way into the engine oil, causing dilution. Which is bad for internals.

And why would a fleet vehicle have a tuner on it to begin with? Unless it was just used for monitor. Does the truck feel like it has a tune on it?

[Lccountryboy89]

well it was originally a fleet vehicle (that's where the majority of the miles came from but has the complete service records) and then an individual bought it. and the tuner was set to stock when I test drove the truck.

[kdogg85]

That would be my only concern is having the truck reflashed because of the tuner. Most would say the tranny, but having a tuned truck before, I'm sure you would know what to look out for on that subject. Someone with that knowledge will chime in, I'm sure.

you don't have to have it re-tuned after the bully dog. just buy an H&S and you're good to go

Or buy a spartan.

how much is a Spartan tuner that has a gauge readout, changes power levels on the fly, and turns off TPMS?
