well as we all know ..free flow air box and free flow exhaust will give you better fuel economy and higher horsepower
so would not a tuner box give the same results ?
I am amazed at the mileage some of you are getting with stock 5.4's so much better than me

From: Ontario
About exactly my commute with the same results except I am basing my numbers on what is shown on the dash.
And I thought I was the only fool driving 100km each day to work in a V8 truck! I've considered (and been advised) getting a little commuter car but I LOVE this darn truck. It is depreciating rapidly with the miles I am putting on it but I've decided I don't really care as I am going to have it till it is old old and then it will stick around as a third vehicle on the farm.
Since there are a lot of Canadian boys here - do you guys do anything for rust control like Krown on your vehicles?

I figured keep it maintained. and it should last me. Maybe pass it on to my son when he gets old enough.
As for the winter, I've got mine undercoated.

yes. I too have been advised.. but same. I love this truck too much. I bought mine Sept 2009. I'm about to pass 45,000kms.

Yes, that's the secret to fuel economy, more power and advanced timing. Do you mind if I contact the Big Three with your breakthrough discovery? They might want to borrow your magic tuner box.These trucks do seem to run a bit on the rich side. Mine only has ~2200 miles on it and it has a fair amount of carbon build up on the exhaust tip. It might lean out after it breaks in some more, but I've seen other reports on this too.
There are a lot of reasons a manufacturer may choose to run the engine rich. An engine makes the most power at 14.7:1 - but pulling some numbers out of my ***, 12.0:1 - 12.5:1 is probably more like the normal accel ratio. The thing is, it's probably not necessary to run that rich at 50 degree's and low humidity -- but it probably is necessary at 110 degree's and high humidity.
Also, they richen it up a bit to account for fuel anomalies.
I guess what I'm saying is that Ford has chosen to make fuel economy compromises for reliability. A skilled engine tuner can bring some of that fuel economy back without adding much/any risk.
It's not rocket science, and it's true - so stop acting like a dick when you really don't know what you're talking about.
For the record, I'm at 13.2 average on the computer with this winter gas.
