Unfortunately their program only works on a PC, but I have a Mac. I will probably end up seeing them sometime this month to have them stiffen it up quite a bit
Double check they did not give you the plush tune, they offer 2 tunes out of the box. Someone might have mixed up and given you the wrong one. If the back end of your car bounces up and down a couple of times very springy when you go over highway bridges, I believe you have the plush tune by mistake.

The single biggest measurable improvement is that I can visually SEE that it was done. Too much guessing work with the GM update. You pay them but did they actually flash it? There are a few threads on this very forum that suggest the difference is so slight that you can't even know for sure if GM flashed it after giving them 350.00. With how badly they messed up my alignment I'm not about to trust them with something like that.
I didn't take it to the track, no, but the owner, Mike, has with his ZR1. He knows more than enough about track racing that I'm pretty confident the controller is doing what it needs to. The settings on the site and on my controller are the same he uses on the track.
Remember. He is selling you something. I saw the laptime improves published by DSC. I fell for the snake oil a while back. messed with it for over a year. Couldn't get good results. Asked for help numerous times. He never did work directly with the z51 so maybe that was the problem. Never tried it with z06 suspension. But hey, the z51 stock tuning worked fine when i put the z06 springs in.
Just stating facts. "feels better, and feels more planted" are not facts. Better lap times are. I'd like to see people getting measurable better laptimes before/after, same car setup otherwise (not published by DSC). I tested this, and my numbers were no better (technically i improved 0.3 avg lap time but that's what I had been improving every time i went to that track with no changes).
In the street I HATED the DSC controller. no matter how much i stiffened up the numbers, it never got to oem quality. My passenger that knows nothing about cars felt VERY uneasy at high speed due to it. If you like how it rides on the street enough to spend $1400. sure, fine.
I sold it for $700. In my mind i wasted $600 + maybe 24 hours of messing around, research, etc. That's a lot of money.

I feel like if the controller was that bad on the street for you the numbers you were able to achieve on the track would have suffered as well not improved. The controller definitely makes the ride softer, but at the same time I don't feel I've lost any agility with the vehicle. No that is not the technical information you are looking for and even if I made it to the track with this device I wouldn't have the numbers from the stock controller to compare it to. I do agree some official track comparisons would be nice to see, but without them I am still a believer in what this controller is doing. I will be spending more time with it in the future to get more comfortable with it all so I can revisit this later but as of now I'm impressed.
I had the DSC controller on my 2016 and it made a world of difference. HOWEVER, I was able to drive my stock 2019 back to back with my DSC equipped 2016. I felt no difference in any of the modes from performance to comfort. Kudos to DDC for fixing the earlier models, similar kudos to GM for fixing the 2019 out of the factory.
I’d also add my best time at VIR full course with the DSC on street tires was 2:09. My new best time in a stock 2019 has been 2:06.

Wow! If this is true then that is some serious stock improvement! Was your 2016 a Z06? I'm assuming the 2019 was as well? Z07 packages or no?
Both Z06’s, both non-Z07’s. I believe I’m now the fastest non-Z07 at VIR. Poorsha still waxes me regardless.
i should also mention the 2016 had the DSC alignment as well, performed at their Maryland facility.
Definitely interesting. The first time I've heard of a change this massive taking place for the 2019's. Pretty cool that GM seems to be listening. Now they just need to fix their alignment issues!

My 2016 was way off on alignment from the factory. The DSC and alignment did the trick. The 2019 came out of the box feeling every bit as good as my 2016. Track times just proved it. I have no doubt the DSC unit works on 2018 and older models, I lived it. I've not driven another 2019 with the DSC controller so I have nothing to compare it to.

It's funny that you come on here talking about how much better the DSC is vs the GM upgrade, but then you praise the 2019 calibrations.
The GM upgrade is the 2019 calibration, backported to the 2014-2018 cars.

I would definitely like to see what your car would do with the DSC unit just for giggles but it's still awesome to hear a real life experience with both!
DSC has a new tune file available, I haven’t loaded it up yet but here’s my take on the whole deal. I haven’t driven ride update car but my 2017 supposedly has the updated track settings the new GM suspension calibration comes with.
if you just drive on the street, do not buy a z07 car just get the GM mag ride update.
if you have a z07 and want comfy ride get the DSC.
if you have a z06 (non z07) and you like a firm/agressive ride in tour and sport dont Get dsc unless you want to modify settings or to put on z07 springs and shocks. (This is what I did)
the dsc on the stock z06 springs (with as loaded 12/17 calibration) felt too soft unless I was in track mode. Edit( I fixed most of this by modifying the G comfort setting in tour and sport. ) Which I guess I could have just driven in all the time looking back at it with perfect hindsight.
for what it’s worth the DSC alone improved my body roll in my z06 on stock suspension but it softens the shocks so much without speed or G force input that non-track turn in feels softer than stock settings when you’re cruising back roads. It comes alive when driven aggressively or in track mode.
Adding the z07 spring/shocks brought my street driving feel up to what I wanted. Its hard to look at this and say hmmm wasn’t it all worth it over the GM ride update but I’m a car nerd and enjoyed the journey and wouldn’t take it back. paid $400 for all the z07 parts and $900 for installation + $1290 for DSC. So it has been an expense but I do really like the ride and feel now. Very happy with this car. Need to get forged wheels so I can focus on driving and less on dodging potholes. If you figure a z07 car with visible carbon aero like I have costs about $11000 more im way ahead.

just left DSC
we stiffened up tour and sport mode by 25% and track by 40% . we secured a slightly loose pinhole on the oem harness.. Also updated firmware.
much much much better. no “service suspension” errors!!
huge thank you to Jeremy, Marko and Tom for taking care of me as usual.
ive been a customer of TPC since 2011, my fav shop by a mile.

Thank you for this update. Can you detail *exactly* what was changed? Did they modify G comfort settings or the underlying shock tables?
lets let Jeremy explain. lol im not sure
but it does feel much much better. still compliant in tour mode but no more cadillac-like oscillations over dips.

I feel like DSC should be a little more detailed and offer more canned tunes to install. Everyone I’ve seen on here complains of that oscillation or porpoising of the as stock dsc controller
