I should preface this by stating that I'm an old V8 guy. Thus, my answer will be biased.

You should ask one of the highly esteemed EcoBoast guys on here.

Rock on!

Have you recalibrated your Speedometer to your larger size tires… I’m lucky if I get 15 MPG!

Yes Husker, as stated above, speedo is corrected.

The mileage is slowly dropping back to normal or thereabouts.

I'm thinking that the computer is relearning and adjusting.

I am tracking. By the way, my lifetime on the clock reads 19.7. The lie-o-meter is exactly 1 mph high.

Oh, and lovin the sound!

Same here...when it was NA, now we won't talk about MPGs.

SPOAT's mileage is pretty amazing. What gears do you have?

Once a month, we make a 400 trip on 55 mph back roads across and through north Georgia and north Alabama. We made three trips during December. Same roads and conditions. Lots of small towns and some horse trailers and farm machinery and rolling hills.

I set the cruise on 57 mph. I always average 24 mpg on the lie-o-meter. That's actually 23 in real numbers. Well documented.

Before I leveled the truck and with stock tires, she averaged 25 on the meter.

I'm interested to see if the duals will make any difference on our next trip.

Don't forget that I have the 3:55 rear and with the 34" tires that equates to a ~3:30 rear. Maybe that's the difference.

My bud has an identical truck to mine, but 2WD and he has the 3.31. He get even better mileage than I do.

Either way, forget the MPG, embrace that new sound!

3:73...I don't really keep track of MPGs because I know my lead-foot + V8 + 34" tires + 3:73s + Paddle/Manual Shifting (I keep the RPMs up) + Jack-Rabbit Starts = LOW MPG = FUN!

I guess that's probably key. Highways seem to be great, freeways are not. I can actually relate to those MPG numbers @ 55. Too bad our freeways are all either 62 or 68 mph, and literally nobody actually abides by the speed limit, so more like 68 or 75 mph. 3.73 gears kill me at those speeds because cruise rpm is closer to if not 2000. Add to that the fact that the entire city is like downtown driving, and that's probably why Fuelly says I'm at 16.7. Husker is probably right; using Fuelly is a carryover from driving the Canyon but I should be having fun with the Coyote instead.

If you ever get the chance, even a smartphone will work for sound! Obviously it's not representative of the exact sound profile, but it can give a pretty good idea of what to expect, apart from the usual it's-louder-in-person business.

Wasted an hour and five gallons of gas trying to record the sound with an iPhone.

And yes, even tried a remote mike. Terrible results.

I may attempt to tape a Bluetooth mike to the rear.

This example is very close.
