I just let my Q50 go last Friday, so no need for this any longer. Worked great, really woke the car up. If desired, the upgrade kit to make it into a JB4 can be purchased from Burger for $100: Q50/Q60 Stage1 to JB4 Upgrade Kit
Also comes with USB cable to adjust boost levels. I'm asking $330 OBO.
Hi, I'm super new to this and I was looking at a JB4 Tune for my 2017 Q50 Silver Sport, I was if I would have to get better air intakes and or an intercooler if I got the tune. I know it's a very dumb question but I'm very new to this.
