I have had good experiences with them on other platforms. APR is pretty pricey for just a tune, if you go with Protomotive - the following 3 updated tunes are free, this is great if you decide to mod further.
I heard APR has recently hired 10 engineers to work Porsche tuning, especially with later year models.
What sold me on the APR tune was that the owner of APR owns(ed) a 996TT. Still liking the tune and can hardly wait for the next track day!
I used APR on my allroad 2.7T and it was a great tune. No issues with it whatsoever.

APR is a class act. Have visited their facility a few times, have experience with them with my A4. Glad to see another competitor in the mix.
Funny because some of their (older) logos include Porsche tuning - seems like they started doing some Porsche work, it didn;t go too deep - then focused more on Audi/VW...guess now they are adding more support for Porsche.
Start the car, turn the cruise control on, depress the lever until engine light blinks 1, 2 or 3 times in succession. Let off the lever at the chosen tune and shut off car. Turn key on without starting for 10 sec and then turn key off for 10 seconds. Wait 5 seconds start car ....good to go. That was from memory so hopefully correct
