I work almost 100 miles from home I commute to and from daily. If I owned a smart car or a prius that would be ok, but honestly what real working class man drives one of those... My truck is out of the questions for the commute so in the summer I drive my wife's Mazda 3. Over the winter as I was revriding my gas tickets from the summer I remembered this site. I looked up a few products that you have had previously for sale, cheap mods. 1) turbonator and 2) stage 2 chip. Both less then 100$ each. Yes they have paid themselves off ten fold. I'm now squeezing between 45-52 miles per gallon vs 25-30 that I was getting. When I order they told me 4-6wks about 3 weeks I got the turbonator couple days after that I got a call saying that the stage 2 chip was out of stock but there was another one that was the same but a different manufacturer. I said to send it and thanks for the call, a week later I got the part. Installation was a breeze. Thanks
