Tune and charging battery Question
After I upload the tune, I understand that I need to unplug the battery overnight. Just the negative cable ok? At that point, I have to charge from the battery itself, correct? Where do I clamp the negative cable in the trunk? I can't locate an appropriate spot. Thanks for the help.

Just disconnect the battery overnight. Then reconnect it, start up and go. That’s it.

Only if it’s low. Stick it on a charger if it makes you feel better. If it has enough charge to start the car it’s fine.
