SCT/Superchips - changes shift points (is that what it does?)
Cool air intake?
Straight pipe exhaust?

I doubt that there will be any fuel mileage increase with any of the options you have listed. I have tried K%26amp;N filters and exhausts and have had zero increase in mileage. Might get a little horse power bump, but no increase in MPG. Best things to do are make sure vehicle has properly inflated tires, energysaving lubricants, drive with a light right foot and make sure vehicle is in good tune (plugs, airfilter etc.). Sometimes on older higher mileage vehicles (+75,000) changing the O2 sensors will help.

Fuel Economy Improve for 2004 Dakota? which of these may work the best?Hi Jon,
Are those my only choices?
MPG gauges are good because they keep the driver more concious of their driving and will be much more likely to pick up better economy driving habits.
PROM Chips may possibly offer a little, but not much more economy due to a modified timing curve. Late or held out shifts certainly dont give better economy. Some chips are plain lousy unless you use premium fuel.
Cool air intake will enrich your system and make it use more fuel.
Straight pipe exhaust could increase efficiency of combustion, but for most applications it would only be at or near wide open throttle which is hardly the thing you would want to do if you were talking economy of fuel.
Actually of these things you'll probably get the most benefit in mpgs from the scangauge. Oddly enough, when you know how much mileage you're getting you tend to find ways to alter your driving habits to make you get better mileage.
Exhaust-Nothing.
Intake-Maybe if it makes you leaner.
Shift point changer-Maybe in the city, but probably not on the highway...but it's not something you want to mess with in an automatic vehicle (in my opinion);Fuel Economy Improve for 2004 Dakota? which of these may work the best?
