    Hey everyone, I have a 2021 Q50 Luxe. I notice when I run Map 1 on 91 octane, whenever I full throttle the car, it's very slow for a good 4-5 seconds, and the rpms VERY slowly go up, then the boost kicks in, and the car accelerates quickly.

  16. What Did you Do to Your Q50 today
    Naturally, I decided to install my new JB4. Installation Installation went well, the actual hookup took less than 5 minutes, even though I skipped the fuel wires because I would rather find some piggyback harnesses instead of a Posi-tap. However, I decided to do the OBD cable the "right" way...
