Max Mileage Module
I got one about 2 weeks ago. Only went through one tank so far and it has increased it, I haven't run the numbers to find out how much yet, but looking back at the same time frame in the past years it seams to have increased by about 1 to 1.5 mpg. I am waiting to get more miles to check the average.

I've had one about a year. To do it again, I'd save the 180 bucks. I never noticed much change in the paper calculations but it sure screws with the evic. Evic says I'm getting 20 with the infamous module plugged in. Paper says about 14, the same I got before donating to quadzilla. Truckbouy2 product review......Thumbs Down

I have gotten a solid .5MPG increase having used mine for about 25K.
You see the best increase on nice unloaded highway driving. city it dosen't help to much and towing on the highway I also saw a nice bump.
It also made my overhead just about right most of the time.
Thanks,
Jay

I am happy with mine. Been in use for almost a year and I have gotten 1-2 mpg gain very consistently. I do all hand calculations and my over head is still about 1mpg higher which it was before the MMM. Mine has easily paid for itself now.
