Previous Audi owner here chiming in to offer some perspective. Briefly touched on by Lionel_Hutz, the VAG tuning market has a much stronger foothold when compared to MB cars. Obvious answer to this is lower economic barrier to entry - VW's are lower cost, but share the same engines with the premium Audi side.
Audi/VW has a networked diagnostic system that automatically flags reflashed/tuned ECU's (APR, GIAC, etc). Mechanical/ECU issue, the tech connects to the car and runs diagnostics. When a tuned/modded ECU is detected, the VIN gets flagged with a "TD1" designation that alerts service techs to possible modification. Cars can also be manually flagged by techs upon visual inspection of things like exhaust, intakes, etc. This basically gives them free reign on approving/denying warranty repairs on anything potentially affected by a tune/mods including intakes, exhausts, tunes, supercharger pulley upgrades, etc. Of course, if you were TD1 flagged and had a window issue or suspension failure, they're not going to deny that, so the warranty is still valid. But once the VIN is flagged, it's flagged for life...no longer eligible for CPO for future resale either.
Piggyback systems ARE detectable after being unplugged from my understanding, but only upon deep manual inspection of logged records and manually flagging as TD1.
While it might not be the same automated system Audi utilizes, it wouldn't be unreasonable to think that MB would have a similar system to flag a VIN for possible modification related issues to consider when turning in warranty work.
YMMV

I vaguely remember many years ago new M3 owners were having problems with their engine or transmission within months of taking ownership. When taking the car to the dealership to get warranty work done, the dealer read the ECU and was able to identify different times that the engine was near redline during the break-in period and thus held out on replacement due to improperly breaking in the engine.
Was the replacement eventually done? Were any mods detected? I don't know.
What I do know is that service can read the ECU in as much detail as they want and can thus detect any changes. As others have pointed out, they also have the burden of proof. I don't know how high a level has been established.

On the detectability of piggybacks, my understanding is that it will vary between cars and between manufacturers, which is exactly why it is important to understand what Dinan is doing with this tune. For example, on the JB1 for VWAG's 2.0t engines, the box intercepted enough sensors that it could safely spoof data and the ECU never "saw" the actual boost that the car was running. I understand that other cars may have ways of permanently logging when boost is outside of factory range.

Guys, I spoke with our rep and Dinan was extremely busy today. It still isn't certain if they are shipping today but they promised no later than tomorrow! Will keep everyone updated as I get more info.

I'm worried about boost spike which could cause possible check engine light issues. I have had boost controllers in my previous cars (STi, Evo, GTi) and don't want the headache dealing with it.
Not sure if this is a good idea in the long run....

I normally just keep it in sport and when I actually want to go extra fast put it on race.

Does it recognize more than one setting through Comfort, Sport and Sport + mode? You have mentioned Race mode??
C43's only have Sport + for maximum power delivery.

You're confusing the boost controller settings and the car's mode settings.

Yeah.
The Dinan Bluetooth application needs to have some improvements but it works fine now.
I would like them to have the mode selected highlighted (right now it only changes the psi # so you have to know what the psi is for each mode to know which one you're using).
The other thing I would like to be updated is for the boost readout to leave an extra clock arm for 30-60 seconds showing the highest boost you reached. Right now it updates instantly so it's hard for me to tell how much boost the car makes in stock vs the Dinan modes. For example, I might have misread the boost but it seemed the car hit 17 psi in race mode.
