Mini Maxx and Drained Battery Problem

Hey guys, It's been a long while since I've been on here. Haven't had any problems at all with my set up (mini maxx HD300, 5" DP Back, Intake) until recently. I have recently noticed that something is draining the batteries on the truck when its sitting. If I don't drive it for about 2 days I'm having to jump it.

I don't think the batteries are bad. I think it is the tuner draining it. Any thoughts or experiences? Oh ya I have it powered directly from the port and not the ignition. I do turn it off when the truck is not running. I also noticed that recently the following would happen.

1. I turn on the tuner, wait for it to boot up.
2. Turn on ignition, start truck
3. Tuner shuts off and reboots by itself???

Normal. And the tuner would not drain your batteries in 2 days. Why don't you connect the remote lead? It's easy and makes operation simpler.

yup, takes a minute to wire up the key-on

the mini won't drain your batteries if it's turned off. I suspect you're leaving it on which also racks up engine hours
