I originally was eyeing at APR tuning. Then I found Cobb Accessport V3: https://www.cobbtuning.com/products/accessport/volkswagen-accessport-v3-gti-
mk7-2015-2017-usdm
With APR you have to go to the dealer and pay each time you flash your car.
With Cobb Accessport you get the device and can flash anytime anywhere and
how many time you want.
Performance gains seem not much apart. Anybody has experience?
