You should in general use more cuts than boosts, then boost up the master volume. The key to a good mix though, are also filters (more than EQs if you're good with them), panning and, especially in your genre, compressors and limiters. Seriously, compress the fuck out of it, put a limiter on the master, and there you go. You can filter the lower frequency range of the voice, too - it's better than boosting the other freqencies in terms of quality loss.
(And yes, I'm aware that FL isn't the problem with this - but seriously, a bit of Massive or Absynth would enhance your sound alot)
