Re: sct livewire questions
Don't waste the money on batteries. Its normal to drop down like that while cranking til the glow plugs go off and the alternator kicks in. If your that concerned about them then pull the batteries and get them load tested. If they are coming up the 13.5 though you have no issue.
I would guess the elevation is your boost issue. I can say that I am running the Livewire in my 6.0 for gauges right now but will adding a pillar as soon as funds allow. Not a big fan of the digital ones.
