Jr, let me see if I can interpret what you're feeling into a more tangible format. Correct me where I misspeak.
What you probably expected changing modes to do was: 1) increase suspension frequency and 2) reduce body roll, dive, and squat. Dramatically. Those changes are the things we've come to expect with higher rate springs and damper settings; the increased body support is something that all drivers
particularly appreciate because controlling body attitude is easier the stiffer the suspension gets.
But with magnetic ride, that's not what happens. The steering gets stiffer, the exhaust gets louder, and there's a weak reduction of body movement--but it feels like the change should be 3-5X greater. Did I get that right?
-----------------
The OEM controller settings on the V-series cars doesn't change things like a stiffer set of springs would. That's partially because it can't; only a fully active system can "push" the wheel down (acting as a variable rate spring) whereas magnetic ride shocks can only change the damper rate.
Even at full current, magnetic ride shocks can only
slow down the fluid passing through their orifices; they can't completely stop the flow, so any steady force applied longer than a few seconds (like a continuous high-G turn) will bypass the shock valving and rely completely on the springs and sway bars to counter it.
-----------------
I love magnetic ride and would never replace it with a custom-valved KW Variant 3 like I did on my previous cars, but that doesn't mean it can't be improved. Coming from a KW Variant 3 equipped V, the amount of pitch and roll from the factory is obnoxious, even in track mode. And to me, I didn't initially understand why the engineers didn't dial those things out better.
After digging into this more, the roll/pitch allowance is what enables these cars to perform like they do with skinny tires; weight transfer improves traction. However, when you add power and add rear tire, you might not need or want that amount of squat anymore. Or you might never want that amount of squat; if you're into doing HPDE and never hit the drag strip, there's no point in allowing squat. Same for body roll; once you get some sticky tires and up the power level, the amount of body roll can be excessive.
IMHO, the DSC Sport V4 controller needs to be brought to the ATS-V and CT4-V BW with a proper tune. That controller is faster and can theoretically do a much better job limiting body roll and other undesirable factors, according to reviews. It's also tunable, meaning that you can swap out the OEM springs for higher-rate springs and not have an punishing + underdamped ride. It can also give your Tour mode a more limousine like ride.
I have reached out to DSC Sport to enquire about compatibility with the ATS-V and like I said in other posts, the response you get from DSC is unpredictable depending on who answers the phone. Some of the seem to think that the controller will work on any car. Others think that the CTS-V model won't work on the ATS-V. Some say (and I know for a fact this is true) that development of a custom tune for the ATS-V has to be done by the end user, other say it's automatic. It's a real confusing mess over there at DSC. Therefore, purchasing a DSC Sport kit fell in priority below finishing other parts of my car, but I will eventually get a controller and set to work.

I'm currently running Swift springs front and rear at the OEM rate; I developed a kit for the ATS-V, CTS-V, and Blackwings that will allow you to use any standard 2.5" spring on the market. You could use my kit to change the springs to whatever rate you wanted, but I wouldn't stray away from the OEM rates until we have a tunable controller.
