what is the best chip or tuner to put in a 2005 F 250 with a 6.0 psd. Also I want to know if they cause any damage or void warrantys ect...

 

SCT X3 is a very good product for your vehicle. Aftermarket products have to be proven to cause damage by a dealer to void warranty. Find a dealer that is mod friendly.

Jody Tipton of DP-TUNER has a street tune that gens. 20 MPG. on the highway at 72 mph. (hand calculated) of course. This is combined with an intake and cat back exhaust for the 6.0
--and can be loaded on the SCT.

 

In all honesty, a chip/tuner may not even give you higher mileage. That depends on to many variables and what gives one person 20 mpg doesn't mean that you'll get that with the exact same tune. Other then a couple of higher spikes for one or two tanks, I basically run the average that I get when my truck was stock(I barely remember that day). Don't fool yourself, chips/tuners improve overall performance first(rather that be towing or just driving around town), mileage is a bonus if you get it, but don't think because someone else is getting 20+mpg with a tune that your going to get that same mileage with that same tune.

If you do stick with getting a chip/tuner, then make sure you go custom as those have far better results then going with an "off-the-shelf" tuner. The two that I know of that have very solid reputations(and there are others, but only two that I know thru experiance) is Matt at Spartan Diesel and Eric at Innovative. I would also suggest an aftermarket exhaust to help out, but you don't need to change out the intake on the 6.0 as it has been proven over and over again that the stock airbox is good for 500hp(which I have just barely hit with my mods) and the only way that your going to flow the extra air that those aftermarket intakes is if your high in the rpms(which most aren't going to be). Also a good set of gauges as well to help monitor vitals.

Yes, chips/tuners can cause damage and yes they can void your warranty. You might be lucky to find a mod friendly dealership to do most of your work at home, but if you get stuck somewhere else having to get repairs there is no promise that they'll extend the same good favor to you. As far as having to prove that the aftermarket part directly caused the failure or not, that has a yes and no answer. Yes they would in a perfect world have to prove that it was a direct cause of failure, but no they don't have to do it because more then likely you signed an agreement for arbitration as first venue and then court second(most courts will uphold arbitration like this because you signed in voluntarily instead of being forced to go to arbitration, so going to court second is a moot point). Now I don't know any of the local arbitors around here, but I'm sure my dealership knows a few and I'm sure more then likely they are on friendly terms with those arbitors as well, so I don't think the outcome has a good chance of being in my favor.

Just some things to think about.
