I had Gillett Diesel in Bluffdale, Utah put it in (800-638-4679). $999 installed, ($1064 OTD). Took about an hour to install. Worth every penny so far. Took at trip up north for the weekend. Refueled and hand-calc read plus 1 mpg (vs before Edge) on only half tank used since install. Full tank used calc should be interesting.
Keeping my foot off of it will be the real challenge.
