    from what i understand, its not healthy for your motor, or for the MAF. Plus, youll experience some pretty hard turbo lag, due to not having the recycled boost anymore.

    wrong. its done mainly for emissions, and noise supression. bov's, regardless if they recirculate are designed for these purposes. a bov hurts turbo response time.
