Question: Intercooler upgrade before adding more power?

2020 Audi Q7 55 TFSI, about 14,500 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? If I fix it I'll come back and update the thread.

I'd slow the salesperson down here. In Raleigh, insurance quotes flipped a 2020 Audi Q7 comparison for me more than the sale price did. Then the comparison gets honest. When does it actually happen? A day of patience here is cheaper than a wrong part. If the story changes I'll post the new data.

Insurance and tax belong in the comparison, not as a surprise. Ask for out-the-door on the 2020 Audi Q7 with fees, add-ons, and rate on separate lines. If they balk, that's your answer. On “intercooler upgrade before adding more power,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. This is the filter I use when the thread starts repeating itself. If GAP is bundled I'm making them unbundle it.

Walk if they won't put it on a buyer’s order. In Raleigh, insurance quotes flipped a 2020 Audi Q7 comparison for me more than the sale price did. That's the part that actually changes the decision. Time, temperature, and whether it's in gear are the notes that actually help a shop. Worth doing even if the car feels fine right now. Doing the boring step first on purpose.

I'd push back a little: In Raleigh, insurance quotes flipped a 2020 Audi Q7 comparison for me more than the sale price did. Screenshot the worksheet if you can. Write the result down so the next test isn't a repeat of the last one. Going to compare one more dealer before I decide.

I asked about intercooler upgrade before adding more power again and they still won't put GAP/add-ons on their own lines. Not wiring anything in the meantime.
