Still considering my options as far as other mods. On the one hand, sure, I’d love to have a mid-11-second car (ECU flash), but on the other hand, the car is CPO, and I like having a warranty…
Honestly unless you plan to go all out yeah it doesn’t make much sense. A nice catback may be a nice middle ground tho? Can you upgrade the ecu with oem because isn’t the latest tune like 450-460 and its essentially the same car?

If I were to do anything with the exhaust, it would be to delete the center resonators and install an x-pipe. Car sounds great with that setup, and it’s pretty economical to do.
Audi’s 2015 “update” that supposedly liberated an extra 30 hp (from 420hp to 450hp) hasn’t resulted in a commensurate increase in performance, from reports I’ve seen. The 4.0TT’s output has always been WAY underrated, so my guess is that nothing really changed, but that the rated figure is now 30 hp closer to reality. The true output has always been between 480-505 hp, depending on whose dyno or test you read.
ECU flashes for the C7 are more like $1,300.00-$1,500.00, and increase true output by between 70 and 120 hp, again, depending on whose stats you read. Real-world testing shows a 0.6-0.7 second reduction in 1/4 mile time, with trap speed going up 6-10 mph. In other words, a pretty big difference.
All of that said, if I did any of that, goodbye warranty!
Depends on dealers but it’s safer to not. What’s to say any previous owners didn’t mod take back to stock and reflag wh ecu u think any cpo exist like that. I bet there are some

I’m sure that’s happened at some point, but Audi is getting more sophisticated and smarter about checking, so even flashing back to stock may not avoid the dreaded “TD1” flag. If they choose to look that deeply into it, they can see how many times an ECU has been flashed/updated, and if that number doesn’t match the OEM update record, the TD1 flag can be the result…
I am wondering if a company could clone an engine ecu so that the immobilizer and VIN info is right so that a customer could swap ECUs before they take their car in for dealership service. Kind of like how you can plug and play swap the ECUs for the B5s.

The wheels look good.
Sounds like it would conceptually.
But Honeslty how many people who lease or buy these brand new then tune them. And then how many of them remove the tune after lease turn in or after sale. Almost all rs7 you see or s8 or any car north of 70k is cpo
Actually from my m5 experience it was catless and has a tune and they would still cpo it but it wasn’t worth it as t was only 10 months more of S coverage due to being an 06. I didn’t have a cpo but my s6 was modded albeit lightly and had zero issues with any warranty repair at the dealer.
If your good with your service dept usually you end up ok but jimmy probably knows more
