The best way to increase fuel mileage is to use your brakes less.
Here is something to think about before you rush out and pay to have your tires filled with nitrogen. If you notice service stations never say they are filling your tires with pure nitrogen they just tell you they are filling the tires with Nitrogen. The atmosphere is approximately 78% Nitrogen so from a legal standpoint the normal service air at the gas station can be advertised and sold as "Nitrogen" because it is more than 50% Nitrogen. Additionally even if they do fill your tires with pure nitrogen and there were any benefits of doing so, those benefits would not be seen because even a flat tire is already full of air from the atmosphere so the only way to get pure nitrogen in your tire is to stick the tire in a vacuum chamber to remove all the air then refill the tire with pure nitrogen.

It should help as long as they use the 5 tire rotation method so the spare gets rotated also.

Hey, all jokes aside, here's some info. I bought an Edge programmer for 200, and a used set of Troyer underdrive pulleys (crank and water, I believe they're 20% under) for 100, installed myself. I'm in for 340.00 (add shipping). From my track days, I'm a compulsive data logger, old school with notebook and calc in the truck. I've done almost every tank (fuel cons) since I bought it. I was 11.5 to 13 in town before and now I'm 12.8-14.9. The Edge mpg function has also backed up the long division. So: based on the cost of fuel at 4/gal- every 25 gal I'm banking about 14.00. I fill up about every 10 days. Over the course of 1 year that's a little over 500 I've saved from stock set up. So it's paid for. I have a set of electric fans to install but I'm waiting on the release of a new controller before I put them in (paid 125 for the pair of 16" used Troyer fans without controls). A 2mpg improvement is a 17-19% gain, and in the mechanical world that's huge. I don't start highway driving till summer, so I don't have good data for that, yet.
I'm been driving like I've got an egg on the peddle and it's pissing me off. I'm clentching my teeth when I drive. Not to mention it's pissing every one else off behind me. I'm making the world suck.

Could you explain what you've got going there? I have no idea what an underdrive pulley is.

Be careful spending a lot of money just to save a few dollars at the pump. Mods arent chaep and you can easily spend a lot just to feel better putting gas in it. I have slowed down and use my cruise control as much as I can now. And have actually picked up about 1 mpg. My last tank was 16.8 in the city. My truck is completely stock except for true dual Magnaflow exhaust with an X pipe. Right now I have Motorcraft synethetic oil in it and have some Amsoil waiting for the next change. Hopefully better oil will help out.
