They both work now. But they both read differently. So tomorrow if I have time I will see about adjusting them if I can.
The guy I ordered the board from said it was adjusted to a v-8 already though.
It looked to be right around 4-5 1000 in neutral.
The brothers was more like 6-7 1000.

I think I would tend to lean towards the new one being correct Andy. I know they test them before shipping. I wouldn't be in a hurry to do any adjusting on it
