Ford F250 Super Duty

Just bought a 2008 F250 super duty Ford and I was wondering I live in California is it okay to chip these out and upgrades that. Will that screw with emissions?

My D-P Tuner can be setup to handle a bunch of special tunes--including the OE stock tune. Before you go through emissions, just set it back to stock. I run 80 hp econo mode for daily driving, and it's quite fast with +2 mpg over stock. I tow with 60 hp tow mode, and it feels about like the 80 hp except it holds the gears out longer.

You can contact some tuners directly for their experience with California trucks.

They need to be certified for highway use. And only a few suppliers can do that.
I have been using a Hypertech ECon with great success for 7 years on my 2005 diesel. They have always been legal in all states and Canada.

you would be better off taking this question to the Ford forums over at Diesel Forum - TheDieselStop.com. you'll find people there who have either done it or not and reasons.

We assume diesel 6.4, but not sure.

Anything modified like that has to be approved by the Crazyfornia legislature and CARB board. :doh:

So anything worth doing (EGR, DOC, DPF delete) isn't allowed.

I got to thinking about the 6.4 engine and tuners. 2008 was the first year of the 6.4 Navistar built engine, and it was the first of the engines that would regenerate and burn out the catalytic converter. Ford designed the engine emissions to where they could tell whether it'd been tuned or chipped.

Most tuners avoided modifying the 6.4 engine's ECU programming.

D-P has a SCT programmer for it, however they only have 40-60-80 hp programs--not the 150 custom programs they have for specialized usage on other PowerStroke diesels. They do have a John Wood custom transmission program that changes shifting points, however.

Your best bet (for the buck) might be to change the air intake system and just be satisfied with what you've got. California is just a difficult state to deal with. Us Tennesseans would be glad if you'd take Al Gore Jr. off our hands.

Lol. Love that last answer bamaman. Thanks for all the help. I am happy with the engine I got, but always want more power. I had the cummins before this and the power on that was much better. Oh well I will just keep on truckin.

The price of tuners has gone thru the roof since the EPA cracked down on them. Actually fining one company. If you can find one on Ebay or wherever then I would advised getting new head studs if you plan on upping the HP.
