After setting Two weeks battery is down
It done this a while back so i thought the battery was bad so I got a new one and it still does it. Is it because of all the electronics on these cars? Will it hurt to just unhook it when I have it setting for a while?

It's best to unhook the battery if it's going to sit for an extended period of time. You also might want to look into a battery tender if you're going to leave it sitting often.
There are lots of little things that can drain a battery over a week or two... even a key fob in left in passive mode within range of the car can drain it eventually if the DIC is set to respond to it.

I keep the battery tender on mine as well. Our BMW does the same thing, I think the alarm also draws more if the car is locked so I don't lock the Vette in the garage. Not sure what I would do if I ever left the BMW at an airport for two weeks

You need to do a current draw test to see how much current you car is using once it goes in to the SLEEP MODE. There are many things that can cause excessive curent draw. Your car should draw right around 20-25 milliamps once the BCM goes to sleep.

What do you use to warm up the car parked outside in -20 degree COLD? My old chevy pumped 5 quarts of oil on the street after sitting there following a blizard.
