As far as accuracy goes compared to the edge system, I can't comment because I don't have my cts anymore. I just pulled one of the EGT sensors out of my stock exhaust and installed in the e g r block off plate. I will say I have come across one strange issue since using it though. I have an OBD Link MX Bluetooth adapter, and if I have gone somewhere, say to the gym, and shut the truck off, afterwards when I get ready to go, I guess the torque app gets lost and isn't connected. When this happens, the OBD adapter is trying to connect, but for some reason can't, and with the truck in gear, foot on the brake not moving, it will make the transmission shift 1-2, 2-5, 5-3 and finally back to one. I noticed this and saw it wasn't connected to the torque app, so I just unplugged the adapter and plugged it back in and everything was back to normal. So, now when I park somewhere I just unplug the adapter and when I get the truck started again, plug'er back in and go without issue. What's strange is a guy on ford truck enthusiasts had the exact same issue yesterday and he uses the same Bluetooth adapter.
