Edge programmer, works great never had a problem with it. It's the second one that I have owned the CS is the updated unit with a lot of new options and features. I purchased it in April of 2013, so it's pretty much new, came out of an 06 Ford F-150 with the 5.4L. Works with ford 5.4 & 4.6 also some GM trucks/SUV. Comes with everything that came with it when I ordered it plus a dash pod (04-08 F-150). Programmer has 3 options to choose from- Economy-Towing-Performance. Can also just run it on stock and use it for gauges, I really like the fact that it has a tranny temp gauge. Like I said it has a ton of options. Selling my truck so I have no use for it. Package includes: programmer, all the cables needed, original boxes, book & instruction manual, dash pod, windshield pod(new-never used). I'm happy to answer any questions you may have, best way to contact me is on here or via txt message @ 785-282-8116. Maybe open to some trades- guns/hunting equipment, etc. Listed more than $100 less than I paid just for the programmer. I don't need help selling, serious inquires only!
