The 2010 Raptor/F150 TPMS system is incorporated in the SJB (Smart Junction Box). The antenna for the TPMS sensors serves a dual purpose, it also receives the RKE (Remote Keyless Entry) signal.
The 2011 and up Raptor/F150, has a separate TPMS receiver module that also serves as the RKE receiver module. This system also makes installing Ford remote start systems much easier, as it piggy backs the TPMS/RKE receiver module, plug and play...
Both designs send the TPMS warning to the instrument cluster via module communication line. The high speed CAN bus line is shared with several other modules with data inputs/outputs. Because of the way the the signal is communicated to the cluster, and the way the TPMS modules are incorporated with other systems (specially the 10 being inside/part of the SJB), I believe disabling the system wont be easy or possible without affecting the RKE/remote start functions.
The data received from the tire sensors are given down to the hundredth of a pound; and it does give for what tire (LF,LR,RF,RR). The sensors DO need to be trained after every rotate to make it correct. So the system is capable of giving accurate PSI per individual tire, its just not displayed to the driver. It's stupid, but Toyota and other manufactures do the same thing.
As for the mounting conflict that Reptar asked, yes, the mounting of that particular aftermarket TPMS system that BlueSTI suggested does conflict with the factory sensors. Both the factory and (that) aftermarket sensor mounts to the valve stem. Trying to mount both to one stem isn't practical for several reasons imo. I've seen people drill another hole to mount a second valve stem/sensor in the wheel, but I don't think that's a good idea either. I'd rather try to band all the sensors in the spare, or manipulate the tire sensors themselves, so that they transmit the correct/higher pressure when sitting at atmospheric pressure.
