Great question!

 

Here's what the creator has to say:

See what your car is doing in realtime, get OBD fault codes, car performance, sensor data and more!
Torque is a vehicle / car performance / diagnostics tool and scanner that uses an OBD II Bluetooth adapter to connect to your OBD2 engine management / ECU
Layout your own dashboard with the widgets / gauges you want!
It can use the GPS to provide tracker logs with OBD engine logging so you can see what you were doing at any point in time
It can also show and reset a DTC / CEL / fault code like a scantool. Helps you fix your car and helps keep repair costs down!
Torque also features:
* Dyno / Dynomometer and Horsepower/HP & Torque
* Can read Transmission Temperatures (vehicle dependant)
* 0-60 speed timings - more accurate than just using plain old GPS - see how fast your car is (or truck )
* CO2 emissions readout
* Customisable dashboard & profiles
* Video your journey using the Track Recorder plugin with onscreen OBDII data overlay - a black box for your car/truck!
* Automatically send GPS tagged tweets directly to twitter (for example if you are going on a road trip)
* Massive fault code database for lookup of fault codes from different manufacturers
* Theme support (choose from different themes to change the look of your dashboard)
* Send logging information to web or email CSV/KML for analysis via excel / openoffice reader
* Heads up display / HUD mode for night time driving
* Compass (GPS Based) that won't suffer magnetic interference
* GPS Speedometer/Tracking and realtime web upload capability - see what you were doing and your engine, at a point in time
* Turbo boost feature for vehicles that support MAP and MAF sensors (VW & Golf / Audi / Seat etc supported)
* Alarms and warnings (for example if your coolant temperature goes over 120C whilst driving) with voice/speech overlay
* Car dock support
* Graph data
* MPG
* Able to share screenshots to Facebook, Twitter, Google+, Email, etc
* AIDL API for third party apps, A simple Telnet interface for developers to talk to the adapter, and an OBD scanner.
* Works on tablet devices like the Motorola Xoom, Dell Streak, Samsung Galaxy Tab and Nook
Works on any vehicle that uses the OBD 2 standard (most vehicles built after 2000, but can work for vehicles as far back as 1996) if in doubt check with your manufacturer first or look for 'OBD2' on written on a big white label in your engine bay
Works on vehicles made by Ford, VW, GM/Vauxhall/Opel, Chrysler, Mercedes, Volkswagen, Audi, Jaguar, Citroen, Peugoet, Skoda, Kia, Mazda, Lexus, Subaru, Renault, Mitsubishi, Nissan, Honda, Hyundai, BMW, Toyota, Seat, Dodge, Jeep, Pontiac and many more vehicle makes, European, US, Far East, etc. Some vehicle ECUs may support more/less features than others
The app needs a Bluetooth OBD2 adapter to work. The adapter is small and plugs into the diagnostics socket on the car which gives your phone access. You can find a list of adapters on: http://torque-bhp.com/wiki/Bluetooth_Adapters (Garmin EcoRoute HD adapters not supported)
If you buy one of the cheap china OBD2 ELM327 bluetooth adapters from ebay / amazon, then make sure you have a good returns policy with the seller
Some of the best reliable OBD2 / OBD adapters are the Scantool.net adapter, the OBDKey, and PLX Devices, OBDLink, Bluetooth, ELM327 and other adapters are supported - search on google for themMore features added every release - there are forums at http://torque-bhp.com/forums/ - if you want something added then let me know and I'll try to add it if it is possible! Vehicle ECUs vary in the amount of sensors supported.

 

Thanks for sharing the link/info for using Torque Pro to read these values.

It's what I was looking for. Best part is I already had everything except the custom plugin specific for the 6.7L that other forum members here put so much effort into.

I now can see the tire pressure for each tire "live" on a Nexus 7" tablet.

Ideally this information would be a screen on the built-in dash info center from the factory. In my case, a device dedicated to report and alert on both the truck and assignable trailer tires would be even better (or integrated as factory option, way cool if it were so). The tablet/old phone and OBD reader is a good alternative. You can also read tons of other values as well.

Abbreviated version to get this working for others:
Android device
OBDII Reader, Bluetooth is the common connection mechanism.
Torque Pro (paid version for the App on Google Play Store)
Custom plug-in, I think this is the latest version:

To install the custom Plug-in, you must configure your Android to allow applications to be installed from places other than the Play Store. It should prompt you to modify this setting when you try to install it.

Once the plug-in is installed, go into Torque Pro, select the Adaptor Status, then hit the menu (usually top right, 3 dots) and choose Settings. Choose Manage Extra PIDS/Sensors. Hit the 3 dots menu again and choose Add Predefined Set, choose Ford SuperDuty 6.7 and all of those custom points will be available when you add a “display”.

 

I didn't seem to find a Torque Pro app for iOS in a search of the App Store. Any alternatives that would give me individual tire pressures? Right now I've got BlueDriver, which I switch between my truck and a 2003 Cadillac that I use as a daily driver. I wish it had more parameters on it.

 

Torque is Android only, though I read somewhere they were working on an IOS version or did but under a different name.
The PID values for the TPMS are available in the other thread linked earlier. If your app allows custom PID values to be entered, you can add them yourself.
