BOV is fine before the FMIC... aftermarket BOV or BOV is strongly recommended for running higher boost than stock. But if you have a pipe welded for it stock style, chances are it'll need to be modified or ditched if you switch to FMIC later
I'm with jamie, no offense man, but if you can't handle an air filter then a BOV isn't something to mess with.
If you're looking for a good one to have professionally installed, the HKS SSQV is an excellent choice, the Greddy type RS also works quite well.
