My main question is what is the benefit of this device over the SCT X3 and about to be released X4? Why are other tuners offering the SCT devices for 2013+ but Livernois is not? I currently have the MyCal for my 2013 SHO but am looking in to options for my 2013 F150. I have been happy with my experience with Livernois but to be honest, I have not been that impressed with the MyCal so was hoping to find out why it's the only option from them. This is not a Livernois bashing thread so don't take it as that, but rather meant to learn more about the differences in the devices.
