I do not have any FICM tuning just the SCT so I can't tell you anything about that part, however I do know the new Spartan 6.0L tuning does both FICM tuning and motor/tranny tuning without taking the FICM out of the truck. There are a couple of folks who have purchased it recently and some have been running the beta version. Don't get me wrong I LOVE my SCT!!!!!! Some folks getting really good mileage with theirs. Mileage will depend on driving style. Mine may be a little on the "rough" side! LOL I am not your ordinary grandmother but I do drive a "Granny Truck" ! I am sure there will be may folks come through and give their opinions on this subject.

I think the best bang for your buck will be the SCT Xcal3 tuner. I have both the SCT and Innovative's mild FICM reburn. I'm assuming your 13mpg on the highway is while towing correct? If that's unloaded its very poor mileage indeed and I would assume you have other issues with the truck.

Ride rite air springs in the rear
EGT, boost, and fuel pressure gauges by DiProcol on the pillar

Plus a few other odds and ends...

The FICM tuning may help those MPG numbers. I have the Power Hungry Performance FICM tuning running with my SCT tuning. I get a solid 15-16 MPG with my mixed driving of 100 miles daily on 35's with 6" of lift.

I didn't see any real increase in MPG EXCEPT during the winter months. It may have been the FICM tuning or my use of TC-W3 motor oil in the fuel.
