Go lightly with your gas pedal, switch ALL the fluids to synthetics(engine,trans and axles) tires aired up, front end alignment, if truck has over 100,000 miles new plugs and wires, clean the throttlebody (I like to take mine off so I can clean both sides with a t/body cleaner and soft toothbrush).

You have the 8.1L which will be even harder to squeeze mpgs out of

Welcome to the club David.
If you could get the intake air spinning as it enter the cylinders, or at at least on the leading side of the intake valves, then yes that would help to atomize the fuel into smaller droplets, spread the mix better in the cylinders & enhance combustion & total burning of the fuel, which would improve mpg, but the tornados are installed so far upstream from the actual air entry into the cylinders, that the air has straighteded back out to normal path by the time/distance, so there is no positive benefit to them. The Japanese motorcycle manufactures spent millions of $$$ on R&D on their 4 valve heads & twin swirl combustion chambers to perfect this rotational movement, but the Tornado doesn't sucessfully do this.
Your friend that actually showed a gain from one, probably inadvertantly fixed something else while installing his since he showed some positive results. Maybe he moved a plug wire that was arcing, or cured a vacuum leak, pumped up his tires etc. Now that he's showed some mpg gain, I'll bet that if he took the Tornado out he would still be showing the same mpg gain without it.

Do Pulse and Glide in city driving.
It improves my city mpg by about 15%- cost me maybe 2% in trip time.
Pulse up to the speed limit-completely lift off the gas- you will actually end up about 2 mph above the limit.
Then glide down about 8 mph
Pulse up to 35mph- you'll actually reach 37mph- lift off- glide down to 29mph.
Repeat repeat.
In general one cycle will be about 1/4 mile-many redlights are about 1/4 to 1/2 mile apart.
You will lose very little time- maybe 20 seconds added to a 20 minute trip.Get to know your trip.
Charlie
PS My 4L60E trans -1998 Suburban 1/2 ton- offers no engine braking when you completely lift off the gas- it glides for maybe 3 seconds per mph lost.
