I have the basic SCT with 'out of the box' tunes and I like the idea of running this module but how does it compare?

I want some input, I would like to optimize fuel economy. Is it worth it or should I just use one of the SCT tunes or is there a custom tune I could use with the SCT? I don't place many miles on my truck in a normal week. But on the weeks I need to travel 2+ hours to work that +$75 a tank fill a week gets annoying.

2006 F250 KR - everything stock (second owner). Im running True, Full Synthetic from https://www.hotshotsecret.com/ and the EDT additive. Im on year two without an oil change - oil holding up well even with the occasional Camping trips. Pure highway mileage unloaded is 20 MPG according to instrument cluster/21 calculated from gallons pumped, fuel pump to exact same fuel pump from a measured road trip. Street driving is hovering @ 15.8mpg from the instrument cluster never actually calculated.

If the module isn't worth it then I'll stick with my oils and additives.

After checking out there web site and watching there video, basically this module increases fuel rail preasure lower in the rpm range. That's all it does.
Since you have an SCT tuner already I don't believe this module will help much. I believe the tune is increasing the fuel rail preasure, how much who knows. If your truck was stock this module would help and probably increase mileage.
Just my opinion.

 

Chad - first congrats on being sensitive to fuel economy even though diesel prices in some places in the US are below Regular thanks to fracking (shale) which does a lot of middle distillates (this category includes diesels). Not sure if you compared Ford's baseline numbers to SCTs --- I have and they're very close, plus Ford is compliant with emission regulations, tuners are NOT compliant.

I'm not a fan of tuners and the reason is simple: the OEMs spend tens millions of dollars to research / optimize these engine schemes to be compliant with Federal and State laws (example below -- company does a lot of Ford diesel modeling) and the "tuning community" expects me to believe (when they spend little to nothing on emissions compliance testing) they can do better?

Not buying it

while I see your point and don’t completely disagree, compliance is a major consideration for the OEM’s. What they are complying with is determined by stats, theory’s and political motivations with little consideration for what works best. The aftermarket (until recently) could label their products as Off Road or Competition use Only and maximize combustion and power with little concern for governmental regulation. To assume a factory tune is “better” means you are primarily concerned with compliance and to a lesser degree, longevity (the OEM wouldn’t intentionally create a profile that damages their product). Myself and many others feel like WE own our trucks and can blow them up with tannerite if we want to. Personally, I don’t own a tuner, my truck pulls a camper and takes me to work often and has plenty of power for that but if I wanted to “Hot Rod” it I would and if necessary I would use any sneaky means necessary to thwart the regulations. I’d also point out Scooter down at your local shop, and many other people across the country have been working and tuning on automotive stuff for decades and have a good idea of what works and what don’t. If I wanted more power or mileage and they could write me a tune without going to jail I’d be happy to pay them. Of course its fine to comply, less headache and worry and I understand that works well for a lot of people but I’d bet money the compromise profiles provided by the OEM are not nearly the “best” by any measure including emissions.

 

IMO manufactures have to conform to strict emissions rules for tuning.
Sadly emissions and power/what's best for the engine do not align and you usually have to balance it out...

As long as emissions aren't strict where you are I believe any well written tune is better than factory.

 

I would prefer to keep the thread tightly on topic - 'optimize fuel economy.' Will the pro-module do it? There have been opinions expressed. Thank you.

I do not want to further the conversation on emissions. I recognize there is a tendency to intermingle the two (emissions and MPG) - they do not always correlate but they are not completely separate either.

The third piece is laws/regulations. Im not a fan of my truck bellowing out smoke, and it isn't tuned that way. I am on the OEM tune at the moment. Tunes are allowable for my truck in my county so long is its not running like a coal burning locomotive and I hardly find it unreasonable to make a tune change the emission chemistry so long as the total volume of change is negligible and negated by less fuel consumption.

 

With the known vulnerabilities of our cylinder heads, any tune that raises combustion pressures would be a no-go for me. It's my understanding that the only tuning that is done on the 6.0 that does not do this is the FICM tuning. Someone please correct me if I'm wrong. Maybe I'd consider it if I had ARP studs.
