  • 2017 BMW 320i JB4 questions

    I have a stock 2017 320i corruently and have a few questions that can hopefully be answered. Does anyone know if the JB4 for the N20 fits a 2017 model? On the website they say it fits 2012-2016 i believe. Also wanted to know how adding modifications after a JB4 tune would work or if its the right tune to get if I plan on adding modifications Higher flow dp(still catted for emmsions pass), catback exhaust and a few other things in mind) Does the JB4 continue to tune after I add these modifications or would I need a different tune to keep my car safe?

    You should have no issues with that JB4. JB4 will alter and adapt as needed. Map 6 gives you full control of the given parameters as well!
