I don't know what Mythbusters episode you were watching, but the one I saw was the exact opposite. 45 mph and under, the window rolled down got better MPGs than A/C.

However, I have read that over 45 mph is where the resistance starts to become more of an issue and A/C is preferred.

 

agreed

especially if your Jeff Dunham

 

So according to your own math, in one years time, you will save $97 by getting 16mpg instead of 13mpg. I think this proves all our points.

So lets say you buy a Superchips programmer for $300, and it somehow takes you from 13 to 16 mpg. It will then take you 3 years to pay it off with the money you are saving on gas.

 

3 years!!!!!

 

but i do plan on driving the truck for that long three years aint that long of a period. and that it just at driving 17 miles a day

 

And that's if fuel doesn't go up to $4 a gal!!!It may be 4-5 years!!!

 

actually i was on my way to school today and i realized that i only calculated for one way. this means that it would only take me a year and a half to pay off my superchip.

 

Silver was being overly optimistic.

The Superchips will not net you 3 more MPGs. I used to have one before I sold it: it netted me about 1 MPG more, both in town and on the highway. So take that 1.5 years multiplied by two or three, and there ya go. And that was on the 91 octane performance tune, so gas will be even more expensive. The 87 "economy" tune got me approximately 0.5 MPG better.

If you are dead set on getting one, find one used (and unlocked). Much cheaper that way. Sold mine (1 year old) for about 2/3 of what a new one cost. $150-$200 is better than $300.

What we're trying to say is, a tuner is a fine thing, but it will still take you at least a couple years to make up the difference.

Don't buy a tuner for gas mileage reasons. Buy it for the performance, and if you get a mild MPG increase, count it as a side benefit.

 

Looks good..But it is what it is. Just like a lot of others have told you, unfortunately you really won't be able to get a whole lot more.

For as much as you'd dump into your truck trying to get it up to 16mpg (or whatever), it really would not be worthwhile in my honest opinion.

Silver's suggestion was good. See if you can take a few bucks out here and there from something else (like going out to eat, sheetz, etc.), and put it towards gas or whatever.

Otherwise, unless you get another vehicle, there's not a whole lot to do about it.

Edit: I think I missed the second page . But yeah, like others have said, it's really not worthwhile. if you want to get a tuner, go for it - but don't expect much mileage gains out of it.

 

jasonw, im not too familar with chips and all, what do you mean by "unlocked"?
