2023 Audi S5 Sportback — anyone else: Intercooler upgrade before adding more power?

2023 Audi S5 Sportback, about 22,000 miles. On repeated pulls I can feel the car soften as temperatures rise. Would you prioritize an intercooler before adding more boost, even if the current setup is otherwise stock? Any data points from owners would help.

Owner notes beat generic advice here. On the 2023 Audi S5 in Ohio, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “anyone else: intercooler upgrade before adding more,” that was the fork that mattered for me. If it doesn't change the out-the-door or the repair estimate, it's noise. That's my plan before I call anyone.
