Best strategy for fuel economy/reliability

[WildStyle]

Hey everyone, just wondering what the best strategy for my 2003 6.0L would be for getting the best possible fuel mileage. I'm also thinking about ordering an SCT X3 and getting an economy tune for it if I can realistically expect the 2-4mpg claims.

I'm a tech in a ford dealership so I have access to everything I need to do this, just wondering which strategy would be the best for my truck.

I currently seem to be getting 12mpg in town being very easy on it. I'm am using Motorcraft cetane boost with antigel with every fill up.

Any help is greatly appreciated. Really wanted to get the most mileage possible out of this truck.

vxcf4 and you can pick up that much assuming you havent done anything that kills mpgs like lift and tires or large injectors

+1 on the strategy, that is the one I will be putting on my EX.
Go over to PHP's forum and find out the best strategy for your ficm while you are at it.

No lift, just a level kit and stock 265's on it. No other mods planned, just want the tuner for the mileage and for towing my travel trailer.

What is PHP's forum? Got a link to it? As far as I know the FICM has never been replaced in my truck. I'll have to throw it on IDS when I get back to work and see what strategy it has now.

I have that strategy also and with my SRL tune I get 19MPG's on the highway. Just drove to Texas from Florida and my friends that went along with me could not believe the milage we were getting with 35" tires.

Power Hungry Performance has its own forum, there is a good thread talking about the ficm strategy.

Here you go. The PHP guys are great! The remote programmming is amazing.

Yea sounds kinda like a pain in the *** being in Canada tho.

I'm just wondering if I can reflash my FICM myself using our IDS at work....

I know I can go back with the asbuilt for the PCM, just not sure about the FICM.

I seem to be getting right around 11mpg or so with winter diesel and and the Motorcraft additive. I know this truck should get a lot better than that!
