    well what i can say is it is way more of a managable power delivery.powervalve need to be set just right.alittle less upper power compaired to the 391 but thats expected.really impressed with it so far.

    That's awesome to hear. Did bdt port it or was ports left alone? I was wondering if it could be ported or if it should be left alone
