Is there any pics of where this is?
Too late and I'm too tired to take a picture, but it is the only sensor dead on top of the intake manifold. Pull off the engine cover and there it is. Depending on year of car it will either have two holes with only one screw to secure it or two holes with two screws. My '13 has one screw.
Ok, would love a pic.....car at dealer 2 weeks so all I got is peruse forums and prepare for when I get it back, all goodies ordered or in hand, chopping at bit for my car
It's smack dab in the middle of the intake manifold (circled in yellow), can't miss it. That's the one you upgrade for the tune.

Here's a thread with a video showing exactly where it is:

I believe it's worth saying...it's important to remember to always change the 2/3 Bar sensor BEFORE loading any custom or stock tunes into the car.
Just trying to save you some future headaches that other's have had.
