Ready to Tune - BM3, JB4 or what?!!
Apologies if this been covered before
Mine is 2016 M2 with Akrapovich full exhaust system with catless downpipe and BMC filter. I’m thinking of tuning my car and I’m hearing good things about both, Bootmode and JB4. What are the advantages/disadvantages. What’s the expected hp increase with the current mods in the car. Will I need to change anything with the tune? Every detail will be helpful. Thank you guys! |
