Not to be a sticker but will over time. Not a short time, but time.

"#'s are just for ease of math"

2.50 a gallon regular

2.60 a gallon premium

2.60/2.50= .961% price increase

So on every gallon of gallon of gas I save:

1.08-.961= .0119% Not a big increase, and it will take a time to save it but it does.

Like I said though it is not worth it, if it is purely a gasmileage mod. Performance and a little gain is what you'll see. Performance is great and the gas mileage is alright. Better than stock but not much.

Do the math. By my math it will take more than 60k miles to break even.. and even that was using hypothetical numbers (better than 1.08%, that's for sure) because I've yet to see some real evidence that it buys you any improvement in mileage.

Dadinator has it ***** on.. if you really only see a ~1% improvment it will never 'pay for itself'.

 

Like I said It will take a while but it will pay for itself, Longer than it's worth but I still don't reccommend it if you soul purpose in life is to get every last drop out of a gallon of regular gas. Your right it will take over 60K and I thought I made it clear that it would I guess not.

It won't hurt but it won't help that much.

i get around 12-13 with 265/70/16 in the mountains. i dont accelerate fast or anything but i do have an exhaust leak somewhere. I am sure thats contributing to it a little. I probably also need to get a new O2 sensor

 

I understand that a chip is for performance not MPG. I'm glad your buick is running that good. . . Sounds like fun!

I also don't want to be a sticker either, but. . .
Your math isn't right.
2.50 per gallon to 2.60 per gallon is a 4% increase in cost.
And only a 1.08% increase in mileage. As you can see by this and the math I supplied in the other post, it costs you money. $135.38 per 1000 miles vs. $131.58 per 1000 miles given that you can get the premium for only a dime more. Around Louisville, it is more like 20 cents more.

 

I have a 2005 Ranger FX4 I'm getting about 15/19 mpg, i travel at 130/145 km/h(89 mph) practically all the time, i have an extremly heavy foot. My EPA sticker(i kept it when i bought it) say 21 mi/gal city/ 29 mi/gal highway. i know they highway rating is at 77 km/hr speed, 55 mph? not a very good comparision for epa, we all know highway speeds are 100km/hr 60 mph or higher.

 

Yeah your right I had a decimal place wrong and it screwed up Oh well What ever, I was also figuring the worst case scenario too, I got and average of 22 before and now I get an average of 25. I'll do the real math later, but Like I said before you will never get themoney back for the Programmer, You will get better mileage and at worse it iwll even out.

On my first tank which was 98% city driving I got about 15.6MPG. On my second tank which was 95% highway doing about 70-75mph I got an amazing 20-21MPG. I thoguht that because my city mpg sucked my highway mpg would too but nope. I'm amazed how well it did.
