| I am looking into purchasing the Super Chips Mileage Programmer to improve the mileage of my 6.0 powerstroke. I am wondering if anyone has one of these, and if so, if they work as good as there website claims. I am currently getting 12-13 mpg mostly because about 1/2 of all my miles are gravel roads. Also if anyone knows of a better/cheaper place to get these that would be helpful also. If I get one bought for around $300 I would need to have it improve my mileage at least 1 mpg to break even in a year. | |
