New to BMW performance... looking for opinions and suggestions.
Hey all, glad I found this forum. Just took home my first BMW - a 2013 335Is coupe. I've been a Mustang performance guy my entire life so I'm new to the BMW scene. I'm looking at mods that seem fairly basic and just want some opinions. I've been doing a lot of reading and researching and think I'm interested in doing a COBB tune and a FMIC on my car to start. What kind of gains might I see on lets say a COBB stage 2 93 octane tune and the FMIC? I'm also interested in NOT having to cut my bumper cover to fit the FMIC so if anyone can tell me which one I can install without having to cut would be great. At this time I'm not looking to do down pipes. I'm also looking at the BMS one piece intake as well. Any opinions / suggestions about these starting mods from the experts is greatly appreciated.
And please refrain from telling me to use the search function.
