I have a 2022 m340i in saphire black with quad tips. My question is when you installed your rear diffuser from ebay did you have to trim the end tabs on the diffuser? Great looking car !!!!!! Thnx
@@EHOONS Im thinking either getting a tune like yours, or the intake, if I dont know alot about tuning at all, will it be hard doing burble tuning on jb4?
@twacbow1-162 burble is one thing that can’t be changed unless you unlock the ECU. The JB4 is good because you can take it off for warranty work. Plus you still get some added power. The intake is mostly for sound
