MYLSI is right about the tuning, H&S is the only tuner available that is considered to be "decent." Bullydog and Superchips also have tuners available, but have traditionally been poor options when compared to other tuners. DPF and Urea deletes are possible with the H&S, but any DMax that is '06 and newer will store non stock calibrations, and void the warranty.

With the cost difference in mind, is supercharging a possibility? Forced Induction should maintain hp at elevation. Not sure if the trans going to hold up to added power and all of the weight.

 

... or the diff.

 

I dunno, it should hold up well with regular fluid changes. Unless your talking about the G80 itself.

 

I wasn't thinking of the locker itself so much, but was assuming it's a 10-bolt and that's a lot of weight to tow. I sure agree that regular fluid change would be mandatory in the 1500, but none of that would be an issue if he goes with a DMax.

 

But then again he did say its an Annual trip. So once a year gear oil change wouldnt hurt anyway.
We changed the gear oil and xcase fluid in our work trucks every 6 months cause it was cheap insurance. And they went all over the US.

 

Experience counts - good info.

 

Thanks for all the good points. we never get diesels were I'm at so not sure on warranty claims. On a gasser only have to sudmit tune files on a engine replacement. But even stock it's way better then then my current truck.

 

LBZ! LBZ! LBZ! Sorry.

 

If I have to drop cash on turbo or supercharger and tune and exhaust and Coolers brakes ect.. I still dont think the trans can take it. I looked for a new truck with a 6.2 and tow package none local if i order one i dont get the rebates.Besides its the same money for this dmax after all the discounts.

 

Your trans and diff should be just fine with the addition of additional cooling capacity.
The DMax trucks are better tow rigs hands down. Your truck would likely be more fun the rest of the year with the mods though. Of course a new DMax is under warranty for a long time while yours would pretty much be without once the mods started.
