I just bought this tuner and tried installing it tonight took me 3 times of scuffing it with the scotch pad and cleaning it with the wipe to finally make some sort of connection or I only assume is connection due to the truck showing me no wait to start light and then a crank no start but when i remove the chip the wait to start light appears and the truck starts as it usually would does anyone know what might be the cause?

10/10 service fast shipping easy to navigate the website. Very happy with my purchase will definitely be using fullforcediesel.com in the future, as for the product I’m very happy with it, easy to install very high quality, I like that it came with a template to drill holes and a piece of scotch brite pad for the connector as well as the zip ties to hang the wire up I’m beyond satisfied

So I bought this because my edge programmer flashed my computer and I read where if u put a chip on it, I'll work. Reman module is right a 1000 bucks. I said why not gonna want it either way because this truck needs to be turned up some... I got this very fast and installed it. Worked great and woke up the truck way more than expected. Love they settings although think they could cut a few down by adjusting it some but that's just a opinion.. did some more reading and edge say the revolver offer 150hp vs this one offering 120 so I bought one and what a total disappointment this was. If your looking for more power and towing. High idling in the winter or working off it I strongly recommend this product. I own a diesel repair shop and will be recommending this product to anyone that ask. Also full force was great to inform me about my order as I needed to get my truck rolling as soon as possible
