    Whats up I been monitoring my voltage and at times its at 14.6 which is great but other times maybe at low 13s or high 12s even with ac and headlights once it hits 12.7 it like to charge I obviously cant have this because my voltage to fuel pump drops about .5 vdc from the battery to fp my question is is my alternator going bad or regulator in it and also is there a votage booster for the 2005+ years ?

    The big 3 doesn't fix any problems.... If you are experiencing a voltage issue on a stock set up, I would have the alternator tested for free at an auto parts store.
    Upgrading your ground wire and power wire with a good working electrical system is always nice to have. It helped me carry the amperage I was demanding from the power system when using aftermarket stereo equipment.
