What he meant to say is you could potentially have warranty work denied. I've never experienced that though nor has anyone I know. My dealer did provide the glow plug reflash and egr reprogram and steering clunk fix while there was a pillar full of gauges and 5" exhaust staring them in the face. They waited while I flashed the stock operating system back into the truck. My brother had his water pump replaced on his 6.7l Cummins at 80k with similar mods all under warranty. The dealer liked it because there was more room to work since all the egr parts were in the barn on the shelf!
The cost of a good tuner will buy a lot of fuel. I examined this scenario with my Dmax and came to a conclusion its a waste of time, money and introduces the possibilty of causing damage to the motor. To do a complete changeover, you also need to consider removing the DPF which will put you on the wrong side of the law concerning clean air.
Consider buying a monitor/tuner and change your driving habits, that will save lots of fuel. The Dmax has plenty of power (stock) and the only place you would need a tuner is on the race track.
Aside from efi live, I would recommend PPE w/gauges to monitor EGT,Trans and boost parameters. I have a 2007 LBZ and run PPE level 2 with the Edge Insight electronic gauges, 4" exhaust from down pipe back with no CAT and EGR blocked/disabled. With a leveled truck on LT265/70R18 running 65 MPH highway driving can pull down 21-23 Imperial MPG consistently and I am in Alberta so this isn't flat land driving. You just have to use common sense, if you want to boost HP to the max and have a heavy foot be prepared to do the trans. at minimum. Keep a moderate tune and drive sensibly and you should have no issues.
Instead you would need to get a DSP switch for switching tunes. As for the gauge readouts, the insight will do that digitally or there is always analog gauges.
Delete the entire EGR system. Or if money is tighter, you can simply choose on of Ricks cheaper options. This part takes some more knowledge to install. I am working on an install guide for this part s I have 2 to install this week.Profab EGR Delete
Plug the resonator. This is just a preventative measure as the resonator sometimes cracks letter dirty air in. Here is a link to a purpose built piece or just go to the hardware store and get a plug cheap. Resonator Delete Plug
If you like having the added gauges of the Edge but want an efficient custom built tune, Edge has the product for you. The Insight which allows you to load your EFI Live calibrations onto it. It is reasonably priced.Edge Insight
The call up Adrenaline Truck Performance and Ask For Rob. Rob is very knowledgable with EFI Live and does very good tuning for the LBZ engine like yours at a fair price.Adrenaline Truck Performance
You will have to find someone with EFI Live to load the tuning in for you, Rob could try to assist you with this, or if your truck can sit down for a couple days you can overnight your ECM.
I hope all of this helps, and good luck with your duramax Experience.

I wouldn't have your hopes too high for more mileage, though -- I don't think I know anyone who will honestly say that their tuner has noticeably boosted their fuel economy. Although I've heard plenty of claims on the internet.!
I would not reccomend and Edge Juice With Attitude on older duramaxes though. They keep claiming they have fixed their issues, but the modules keep failing.
Their issue is that they can loose communication with the crankshaft position sensor and leave you stranded until you unhook it. It will freak you out when this happens due to the erratic things the engine does.
Maybe they are fixed now, I dont know the last 3 times they told me it was, it wasnt.
You wont see a big difference. The thing with the edge and many canned tuners is you will get nearly the same mpgs, but have some more power. So you will climb the hill at 55 getting 11mpg versus 50 getting 11mpg.
The gains are minimal and will not pay for themselves for the average person. But if you put on a lot of miles they will.
Lets say you gain 0.5mpg and put on 200,000 miles with diesel at $3.90, thats $2,600 savings.

Theres a little more to it than that.Its not simply add more fuel for more power, burn less fuel for better MPGs.
Its all about using the fuel more efficiently, the MFGs dont do this. THey tune for emissions, then power then MPGs. Due to emissions regulations the timing tables often leave a lot to be desired, simply changing the injection timing to more desireable figures will net more horsepower per gallon as well as more miles traveled per gallon.
Timing is just the tip of the iceberg, there are hundreds of parameters in todays computers.

Not true at all.
This phrase gets to me everytime somebody says it.
Void the warrenty? Doesnt happen. They just simply wont honor some warrenty claims.
If your radio quits working, they cant say its bacause of your exhaust. The law on this is loose, so they can get away with it because it wont be worth your time to fight it, but if they are going to be that arrogant about it do you really want to do business with them?
Check with you local dealership. See what their policy is. My area GM dealership says that if they cannot prove the aftermarket part caused the failure, then it is covered. So If you have a programmer on your truck and your turbocharger grenades, they might automatically assume its the programmer, but they will look into it. If they find it was lack of oiling (more common than the tuner taking it out) then they will cover it. Yes GM requests the print outs and such. But GM has a TSB on aftermarket power devices stating it is at the service managers discretion to determine if the "power-up" device caused the issue. Gm still has the final swing of the hammer though. But I do remember for engine replacement there has to be a minimum of 3 signs that the programmer ruined the engine.
Once a warranty block is in place it applies to everything. Just don't try snow your dealer, they will find traces if they look hard enough. GM also now requires screen shots from the Tech 2 prior to providing the dealership the authoriztion to repair. No approval then dealership eats cost of repair...Even if you remove tune and return to stock the TCM will have a max. torque value higher than stock or in the case of NBS trucks will store the last 10 tunes. So just be upfront with your dealer. If you want big tunes.....well then you want to play then you must pay.
