Negative ghost rider. It’s only meant as a performance option for the older car owners to get the current calibrations. $350.00 from GM performance, your dealer can install it in about 30 mins. I like the improvement.
I picked my car up from the dealer yesterday after getting the Mag ride update. I only drove it about 20 miles after so not a real good test but, I'm not overly impressed. I do notice the steering is a little stiffer and the ride is SLIGHTLY less harsh over small bumps in Tour mode, but Sport and Track feel about the same to me. Not nearly the improvement I was expecting based on the reviews here...Maybe my butt dyno is not nearly as sensitive as some here but...I was expecting a bit more in the softening of the ride in Tour/Sport.
In my opinion, save your $350 if you are considering this just for a driver/cruiser, it may help on the track some how but....it damn sure doesn't make it ride like a Caddy if that's what you are expecting.
The proper procedure is to let the car sit overnight before making a judgement.
Did you do that yet?
Not yet... I just picked it up last night at the dealer and drove it home. It sat all night last night and all day today. I'll drive it tonight and see if its any different.
It MAY have sat 10 hrs after the dealer did the update, I'm not sure. They had the car for 2 days, just not sure when they flashed it.
Why is this necessary on a car that has already been broken in, meaning more than 200-300 miles?
The only thing changing in this firmware update is computer code; nothing physically is changed within the shock body itself.

The MRC damper system has a built-in temperature offset correction as part of the calibration.
Chevrolet Performance recommends allowing the vehicle to sit for 8 to 10 hours after flash of
Calibration and prior to spirited driving. This step does not need to be done at the dealership and
can be done at the customer's convenience. Allowing the vehicle to sit will allow the damper
temperatures to normalize, and the temperature offset in the calibration to accurately reset. The
vehicle is still functional prior to sitting for 8-10 hours. However, the temperature offset correction
will be less accurate, resulting in a less optimized operation until the damper temperatures
normalize.
I made a short drive in it last night before the weather got crappy. Didn't get to take it on any good "test" roads but.... Tour mode does seem a bit softer after it sat over night. It was pretty noticeable now.
I'm still not sure it was worth the money for me but...I can tell a slight improvement in ride quality in Tour mode. In Sport mode, I can't detect any difference but.....Normally I stay in Tour mode.
I didn't mind spending the money for the update though....I just want everything to be current on the car.
Anything that makes it ride softer is a plus for the bumpy Houston roads.

Bumpy roads in Houston...tell me about it. I noticed similar as you in tour mode: more soft but less “floaty”. I actually wouldn’t use tour mode before this upgrade because of the unpredictably at speed. So I took it out West to the hill country for a little more spirited driving in track mode. By far the largest difference I noticed is the Reaction of the suspension. It is much more predictable in its handling when pushed, especially when you hit imperfections. My .02
Just got the upgrade w/ track option for my Z06 w/ Z07 and the improvement in Tour was substantial. On the NYC/ surrounding areas roads, the old Tour was punishing regardless of how slow the car travelled, even at 5-10 mph. The new Tour manages the same bumps - even the worst, poorly-maintained roads you can imagine, so much better that the ride is now very acceptable. Body control is better, but without the previous jarring motions that used to rock the whole car from side to side.
The new Sport felt more compliant than even the old Tour, and definitely not as harsh as the old Sport. However, I had rarely driven in the old Sport so do not have an extensive comparison.
Have not had a chance to extensively evaluate the new calibrations on consistently-smooth roads so unsure if the upgrade would be equally worthwhile for areas with well-maintained roads, or for non-Z07s. For my application, the new calibrations have transformed the livability of the car.
Even on this cobblestones road - Liberty State Park
After putting about 200 miles on my car last night, driving through all types of different road surfaces and testing the different modes, I can definitely tell the improvement in Tour mode for sure, and a slight improvement in ride quality in Sport. I notice the steering feels "different"...I can't say that its any better or worse, but it does feel different. My car always felt stable at speeds so I can't detect any improvement there but.. The ride quality in Tour mode is worth the $350. I guess it really does just need time to calibrate and adjust after the flash.
