SCT tune discussion - currently tune shopping and need suggestions

As the title states, I am in the market for (ideally 2) new tunes. I am not very well versed on tunes, so forgive me if anything I say sounds dumb. But heres what I want:

I want one tune that is specifically designed for unloaded highway driving, that would help maximize MPG.

I want another tune that would be designed for unloaded stop and go city driving. For the city one, ideally I want a tune that maximizes MPG without being too hot.

Heres where my requests might sound dumb, though: I want to maximize MPG without really turning up the engine. I know that high horse tunes and MPG usually go hand in hand, but it would be really nice to just have a couple tunes that are easy on the engine and get good MPG. So is it possible to maximize MPG without running a hot tune?

also, general tune discussion. Tell me what you guys have and how you like it!

My current tunes are just the canned SCT tunes and vivians looney tune. Also have a "looney smoke" tune that came free but I have no idea what it does and I have never used it. For some reason the word "smoke" in a tune name doesnt seem like it would lend itself to good MPG.

Re: SCT tune discussion - currently tune shopping and need suggestions

I use a PHP FICM tune. Regardless of which tune I run (economy, 40, 80, or 100) I find I get better overall mileage (city and highway) and better driveability. Oh, and the 40 is "safe" for non-studded heads. This is just what I use. Others like what they have. I guess it just depends on how you want to get what you're looking for.

2004 Excursion 6.0
New HPOP/HPO system o-rings; Updated standpipes and dummy plugs
EGR delete; Rebuilt oil cooler; CCV collection mod
VR Black Diamond head gaskets and ARP studs
Oil and coolant bypass filters; Shell EC-1 coolant
Rebuilt turbo; 250 amp alt; 6000 watts of brain scrambling

Re: SCT tune discussion - currently tune shopping and need suggestions

I've been running Gearhead's SRL and 8k tow for the last thousand miles or so and like them both, but the SRL is a lot more FUN! I don't have enough highway driving with either for MPG numbers, but around town and commuting to work (about 50miles/day of 0-50mph stoplight to stoplight) I got 15.3-15.4 mpg with the tow and 15.6-16 mpg with the SRL. The hundred miles or so of highway that I did, I preferred the SRL, better passing and better cruising speed - the tow didn't seem to want to be above 70mph. Also NO smoke unless I really stomped on it from a stop.

When I finally get a sct, I'll be going to 1023.
Been wanting to get "ludicrous" for the 7.3 as well. Lol

Re: SCT tune discussion - currently tune shopping and need suggestions

do you stack the FICM tune with an SCT tune? If so what kind of tune does it stack well with?

Re: SCT tune discussion - currently tune shopping and need suggestions

wow those are pretty impressive city numbers, thats only a little less than what I get on the highway with my current tune. Im studded, deleted, and straight piped.. do you have any other special mods that might help boost mpg? or am I just heavy footed

Re: SCT tune discussion - currently tune shopping and need suggestions

I know they are different systems, I just wanted to know if it is better to keep the SCT stock while the FICM is tuned. Other than them being different systems I do not know much about how FICM tunes work

Schober, if you're talking about my mpg, it's an 03 excursion with 216k, EGR delete and 4" diamond eye exhaust. That's it! I do get it up to speed and set the cruise when I can... And the numbers are hand calculated.

2003 Excursion 6.0, 2004 front cover, Stock head bolts, unknown EGR delete, 4" Diamond Eye turbo back exhaust, Magnaflow 60110 catalytic converter (makes the '03 whistle livable), Hellwig Sway bar, Roadmaster Active Suspension, Gearhead tunes - 8k tow or SRL depending on my level of 6.0 paranoia, unknown work by previous owners...
