Cant get trucking out of my sys.

Do yourself a favor and buy the 379 exhd with the 6nz. Go get it programmed by Mr. Haney. You should still be able to get 6.5+ mpg no problem and I guarantee you will love the truck. I had a w900L company truck with a 6nz and that truck, every single day, got 6.5 mpg, and I drove that thing the way it's meant to be driven. Loved that thing, would still buy it if given the opportunity. Once you drive a hood for a while, and I know I've only been driving a hood for 3.5 years, but honestly I don't think I could go back to an aero truck. Anything else I get in I'm like, "where'd the hood go???"

 

The 04 will either have a BXS accert in it or a MBN bridge motor in it. Stay away from the MBN, they are boat anchors. I have a BXS in my W900L with the Bullydog programer on it, as long as I don't have a big oversize load on and drive decent I can pull mid six's easily.

 

Mr Haney can put a older tune on a mbn motor.

 

Hey Tommy just starting out and was considering boat transport as well any info would be appreciated.
I am also in Miami.

thank you

 

Think I would rather the MBN IF possible, but think with Haneys tune the turbo needs swapped out, drop the cats & replace the muffler with a free flow from Donaldson? Maybe a couple of other things? It has been awhile since I have read up on it.
Is Mr Haney posting much anymore these days? Am sure all the specifics to this is posted in the mountains of CAT threads on this forum.

 

Yeah that's a "poor man's" unbridged MBN. It's what I have and gets respectable mid 6 mpg driving speed limits pulling a dry box with no roof fairing. Has 6NZ 2,300 rpm 550/1850 brakesaver file flashed in the ECM. Borg Warner non-waste gated turbo (forgot the #) same turbo as PDI stage 1, M100463 freeflow Donaldson mufflers, PDI extruded honed coated manifold, and last but not least a fuel temp wire. To fully unbridge would need to also install 6NZ cam and pistons which mine are still MBN. I'm happy with the mpg's and power.

Suggest you be patient and keep looking for 6NZ. Upgrading an MBN or tuning an ACERT plus upgrades can easily cost $4,000 or more. I know of people with stock ACERT's who get respectable mpg's (if I had one of those I'd leave stock personally) you will never find an MBN in stock form doing that. MBN's can be found in most '03 trucks and some '04. ACERT's in most '04 and up to '07. Any ACERT manufactured after '07 would make a good battleship anchor worse than stock MBN's. A few '03 trucks have 6NZ check the serial numbers close to make sure what it has.

 

I will try to get my 2 cents worth in, a reflashed acert with the mufflers replaced or the honey combs nocked out of the bottums will get you into the mid 6's for fuel milage.
what I cann't cash flow with me owning my secound truck is how anybody can afford to buy a truck with over 600,000 thousand miles unless you got the cash in your hand, or it was allready overhauled?
the reason is this you are take a good size risk on the motor, beings a overhaul will cost between $10,000. to $20,000. dollars.
the reason being is most C15s or pick your brand make a millon plus miles if maintained properly but buying a used truck ,most times you have a limited history on the motor.
If you can afford the overhaul, then you can also afford a lower miled unit.
There is a reason you see alot of trucks for sale at 700 to 800 miles because the previous owner thought they where no longer worth the risk!
I have a friend that overhauled his acert with 650 thousand miles on 9 month after he bought it because it had electrolisous (or however you spell it) coolant ate through one of his liners nearly through another even the block was in question.
I am not against old trucks my 2001 w900 that I have now had one point three million on when I bought it for $17,000. dollars it had 400 thousand miles on a Cat overhaul with history 475 1850 18spd, my first2000 w900 I bought had 325 thousand mile on 600 2050 18spd and served me well at that time in my life I had to buy a low mile unit to lower the risk of a catastophic exspence.
Just a friendly bit of advice to consider
Also if you don't mind the looks stick with T600 as fuel saveing are there if you look over the course of the year, my brother drives one.
During the summer on a hot wind still day at 60 mph you will not see hardly any advantage in the winter at 10 degrees and windy I lose mpg faster then him we pull different trailers so its not sience, I have a mid roof with a low sided hopper and he has a stand up with a reefer.
Take your time finding the right truck that fits your needs is also important.
