I would be pretty impressed if a dealer tech could tell there had previously been a downpipe installed via digital footprint only.

Since these cars have electronically controlled wastegates running in a feedback loop, you aren't going to see the big boost spikes and rapid spool improvement like you did with old vacuum actuated wastegates when switching to a high flow downpipe.
You seem knowledgeable on this subject. So going back to the first comment about the dealer tracing the race chip, do you think they can actually use the logs against me in a warranty claim if I present the car as stock? Just curious about how much digging they would do or if its something extremely obvious in the logs
