Thanks for the response BC, that is very helpful! I've watched some of the videos of the FI CBE and it sounds amazing. I was just concerned about the level of drone because it is a daily driver, during the summer anyways. I wonder if any other Roadster owners have installed FI CBE... because I know the cabin resonance is different between coupe and roadster. I've driven both and the roadster is actually quieter inside than the coupe due to the interior shape and cloth top. It doesn't have as much booming as the coupe in stock form.
Just out of curiosity, the slight drone you mentioned around 60 mph, it is better or worse with your windows down? Does it disappear with windows down due to wind and road noise? Thanks!
