Mustang AWD dyno as well... Good work!
Have you ever run the JL in 2WD and 4WD back to back? It would be interesting to know what the drivetrain loss is in 4WD.

Or what about 4-low even? In theory it should be the same, but I would like to see the ECU's torque reduction (I actually don't know if the 3.6 has torque reduction like the 2.0... just assuming).

1:1 gear ratio yeild highest power reading. Lower gears or 4 low would show less.

...That's literally the whole point. I want to know how much more the drivetrain losses are in 4-High, and how much the ECU limits torque in 4-Low.

We haven't, and I wouldn't have the staff available to do that as we are all hands on deck getting systems build and out the door. The dyno sits idle, pining to put the next system to the test... haha.

Chrysler Town & Country 2013, 3.6 V6
Hi there! My name is Tomasz Dembkowski. I am from Poland but I use Chrysler Town & Country 3.6 V6 pentastar (2013). I did a lot in a car, for example, changing filters, oils, fluid, sparks, seals, PUG upgrade. I have also K&N air filter in the original place.
Besides everything, after dyno test I am not happy. Score is very low, only 232KM (287KM +/- 10% should be) and the chart is not smooth. I have significant drop around 5000rpm. I do not have "check engine" or any other problems concerning OBD.
What is wrong with a car, any suggestions?
Thank You for Your help.

A 3.6 from 2013 is somewhat different from the 2018+ 3.6, which is what is being discussed here.

You might have better luck in one of these forums:

I'm often occupied, by many things, often at the same time
It funny when someone says the 3.6L makes all of its power high in the RPM range, no power off the line, when clearly it makes most of its power off the line and runs flat.

But I think that I have some problem which I am trying to find out.

Er, I can't sort out these graphs. The title is "stock torque curve", but every line in the legend mentions some aftermarket company. What do the curves actually mean?

They are the stock "untuned" curves published by the aftermarket companies.

For example, just the red line from the Superchips plot.

Aren't those torque curves? HP curves of the 3.6 still show a nearly straight slope from idle to redline.

The thread (title) is about torque curves, but yeah.

(not that you're saying this) When I've been replying to others, it's typically because people are saying the 3.6L makes all of its power (torque) higher in the RPM range and that's why it sucks, why it's a minivan engine and worthless off road (typically compared to the venerable 4.0L). Well, the fact is, it makes a bunch of its torque off idle, and works really well in the JL, and as an off road engine. The JL 3.6L, manual transmission, and 4.88 gearing (with front and rear lockers) is the epitome of an off road capable vehicle.
