I would appreciate any advice I can get here!
Currently have a 2012 335is N54 with Cobb stage 1 tune. I currently have the VRSF 5 inch FMIC, Injen DCI, and VRSF CP.
I was planning to add VRSF Catless DPs and then go stage 2. I apologize if this is a dumb question... but I was wondering if I needed to upgrade my FMIC to the 7 inch version or would I be okay with my current 5 inch? Also would I need to upgrade anything else before going stage 2? Thanks!
