Default To Tune or Not to Tune?

I got a tune in July of last year and I added the IAG AOS close to the end of my driving season here in NY (Nov.) and I garaged the car. Over the winter I've been going out every 3 or 4 days, cranking the car and letting her warm up to normal operating temp (20min) to keep the battery charged.

I know I could use a trickle charger, but that's for another time. My engine seems to be working better, on startups with the AOS, I'm getting water out of the exhaust, that never happened before, not prior to adding the AOS and I've done this crank-up technique the past 3 winters.

So apparently, the blow-by is routed out of my intake back to the oil pan and now combustion is better. I'm wondering if I need to get a tune or am I okay?

I was tuned last July and I added the AOS on at the end of October? I'm just wondering if there is more performance in another tune or if the ECU will just adjust w/the current tune and I'm good?

Take out the battery and stop starting your car, its doing more damage than good.

The rest has no correlation.

You don't need a tune for the AOS - you're thinking about it too hard.

Getting a bit of water out of your tailpipe in the winter is completely normal due to the fact that water is a by-product of a combustion engine in the form of vapor - so a cold tailpipe may cause that vapor to condense. When you turn the car back on that condensed water will come out.

Get a GOOD battery tender and you won't have to worry about the battery ever again.

Some of those brand name "battery tender" are inexpensive
My cheap ass bought (me) and my father in law one for his money pit (06 Nazi sled AMG with 2 batteries)
Like $42 for 2
If designated for one car.....small one is fine
