I have diesel mechanic friends who work for dealerships who have warned me about that. Unless you can get some sort of "factory authorized" setup... doesn't Banks Power do something like that? I have heard that adding certain Banks equipment will not void your warranty. But that may very well be just internet talkin'!
Yes you run a good chance of voiding your warranty by using one of the downloader style programmers. And there is no such thing as a "factory authorized setup"...that is Banks marketing B.S. As to getting better fuel mileage from a programmer, well I got this bridge from London I can make ya hellva deal on if your in a buying mood.

I put a HyperTechIII programmer on my 1999 F-350, a Walker BTM, and an AIS intake. I didn't want anything radical, just a nice increase. The HTIII gave me that and made a big difference in performance. I also saw a 2 MPG increase. The problem with the programmers is once you get it then you have to learn to keep your foot out of it. You have to resist hot rodding it once you get the increase in performance.

As far as Banks or any other programmer or chip manufacturer is concerned, I have yet to hear of one going to court with you when you sue the truck manufacturer for not honoring the warranty (same with exhaust brakes).

Run a SuperChip in my '03 Duramax. Improved fule mileage and power. At first I was using the power, hey it was about like a 4wd Corvette. Fuel mileage really was bad until the newness wore off and I went back to driving like I usually do and then I was gettign 22 on the highway, not towing. Towing a 10k load it dropped to around 12.
As far as the warranty goes.......... Dealer knew I had a chip, matter of fact the service manager took it for a drive to see how much of an improvement over stock. He was impressed enough to install a few himself. Transfer case went out on the P/U and they (GM) thought it was great cause it was just afew miles past warranty and they didn't cover it. Windshield wiper motor failed and they covered that (it was inside the time and mileage window).
Here's the best part, truck had 168,000 miles on it. I was going to be towing with it so went to alter the chip programing. While programing, ran out of battery power, locked up the computer. I was not a happy camper. Called SuperChips, they recommended towing to a dealer to reflash the computer, which I did. SuperChips paid me for the tow ($65.00) and reprogramed the programer for free. GM reflashed the computer and charged be $100.00. They also found that I had 2 weak injectors. The next day GM put a set of NEW injectors in my truck for free, yes, free as in no charge. They were fully aware of the chip in the truck, how long it had been in there and how I was using/driving it.
I'm sure they would give you some grief if you melted pistons or a turbo by abusing it, such as towing while in the performance mode but doubt they would deny a valid warranty claim. Use good judgement and common sense.
Yes a performance chip is well worth the money and will increase both performance and economy.

The only think I can say about Banks is when my brother-in-law had to replace the injectors in his Duramax at 50K miles Banks found him a dealer that would so it under warranty and when he had to replace them agian at 100K well that was on him. And some dealers are more friendly torwards mods than others. My dealer told me when I ask about warranty and mods. Well we just sort of over look them but if the cost is such that we have to call district to get auth to do the work and your moded your perty much on you own.

Have a diablo predator.. in the tow mode it is like stock except pick up 1 - 2 mpg (12 - 13).. break 20 bobtail..
in econo mode can do almost as well but have great power.. but if you use the power you loose the mpg.. it's all EGT.. higher the EGT, more fuel is used..
Don't have no stinking warantee

Thanks to everyone for the info. I understand that the best way to achieve better gas mileage is to drive slower and let up on the gas pedal. The problem is my brain may be thinking that, but my foot doesn't always do it. 
Regarding the long-term affect of using the chip programmer, does anyone have a list of things to pay attention to? Are there any negative affects (besides the high EGT) of using a chip programmer on the engine, drivetrain, transmission, etc.? I'm planning on keeping my diesel for a while and I want to limit any negative impact on the engine's longevity.
Thanks again in advance.

I bought a programer for my F250 6.0 and once I had the thing reading all the fine print they only recommend the tow safe program towing over 8000. Tried it and didn't seem to give me anymore power and got less milage. I'm towing 10000+ so the thing is basically useless to me. Some of the guys that have them use them only when not towing but that's all mine does.

I bought a HyperTech HyperPAC last year with an engine gas temperature (EGT) probe. Since installing my mileage for daily driving has increased by an average of about 3 mpg and with a feeling of significant increase in power. The mpg increase is not as great while towing but is still better than before. This is with a 2004 2500HD GMC/Allison combo. To me, the best part of the deal is having the ability to monitor my EGT while towing to prevent damage to the engine. More power-nice. More mileage-nice. Knowing I am not hurting the engine by running to hot-priceless.
