I had dual exhaust and a K&N filter installed on my F-250 with promises
of significantly higher fuel mileage. Truck sounds good but I haven't
noticed any improved mpg. In fact in the winter it goes down.
Did you notice more giddy-up-and-go?
My 5.4L in my F-150 gets 15 in the city during the summer and 13 in the city during the
winter when consuming oxygenated gas. The problem is that I burn the same amout of gas to go
the same distance with the added benefit of spewing MTBE type chemicals in the winter.
If there's more "giddy up" I really don't notice it. My F-250 has the
same engine as your F-150 but they have different transmissions and the
F-250 weighs a bit more. I've noticed that my son's F-150 with the 5.4L
always seemed to have more "giddy-up" than my truck. I think the big
difference is the transmission.
I have a 3.15 with "Posi"
Up until the 10th generation of Ford's "F" series trucks (1997-2003)
the F-250 and F-350 series were based on the F-150 design but beefed up
in terms of payload, etc. At that point the F-150 was redesigned and
the F-250 and F-350 "Super Duty" series became a separate product line
and differ considerably with the more current models of the F-150. They
still share some common components, such as engines but otherwise are
totally different trucks. Your F-150 rides better, handles better and,
as previously noted, has more "pep" in normal driving. The Super Duty
series are much harder riding and have a "TorqueShift" transmission that
operates similar to the Allison transmission that GM uses in their
heavier duty trucks.
I bought the Super Duty because there was a potential that I'd be
hauling some heavy trailers again, but that never happened. It came
with a plow package prep, so I bought a plow for it. That's about all
the "Super Duty" it has done. If we end up heading south, I'll
probably trade it in and get a F-150 just for a more decent ride.
That all said though, I still like the truck.
