Update:
So here's what I found out, don't buy the cheap Bluetooth dongle made in China it can and will ruin a Tune. It doesn't have safety features built in like the real one,
It is recommended that you use the hard wire dongle OBD11 to USB and from only a certain company.
You need to research this on Torque's website.
Using the Bluetooth dongle is not as accurate and of course you have a delay with results.
As you see it says 725.1 HP at the flywheel, I know that's not right it should be more like 680.
There have been about a dozen updates for the apps since I last used it and it no longer does FWHP, it only does RWHP now.
I just ordered this
