Brian S from Sycamore, IL said, "I did a lot of research before purchasing a programming chip for my 2004 Ford Excursion with the 6.0L diesel (about 6 months worth of research). After speaking with several other diesel owners and the tech folks at HyperTech, I decided to make the purchase of the Hypertech E-con. There has been a great improvement in power and on the hwy I am getting 4.5 more mpg (improvement from 17.9mpg to 22.5mpg). Everything else on my truck is stock. I will be pulling my 28' travel trailer this next weekend and am curious to see the results. I have only had the product installed for about 3wks, but am very happy with it so far."
