IMO if you are storing it for the winter, and don't plan on starting it up every other week, I would disconnect the battery from the car and then connect the battery tender to the battery. Better yet, bring the battery in the house.
Parasitic draw or something. Have the dealer take a look at it. When they can't figure it out find a good stereo/electronics shop that can diagnose it.
The tune is useless
Are you talking about a tuning device? If you have the SCT/Bama tuner you can sell it (not sure if you can use it to datalog on an S650)
Common sense.
If you're parking it for 3-6 months (depends how long your winter is) just disconnect the battery
They tell you to disconnect the battery in their instructions as well. It just makes zero sense to start it every two weeks.
They also don't mention fuel stabilizer at all.
If...
That's only for people who don't properly store a car. They'll go to start it after three months and it'll be dead and they'll call the dealer looking for help.
Depends on what you buy or how much etc
For some parts rock auto is so much cheaper the shipping doesn't matter
But for a lot of other stuff like oil filters it doesn't make sense unless you're ordering a bunch of them. I'll order two for each of my cars and other cars I work on (my moms car...

Check out Steeda's NA build here. There's more to it than headers and air filters.

Here's how you know this thing is 100% bullshit:
They have a device for EVERY CAR
No tuning company worth their salt can cover that many vehicles
'Installs in 60 seconds'
Generic ass increases in mpg and horsepower. +40hp! Increased mpg!
It just plugs into your OBD port. They are not...
Combustion starts in the cylinder head and goes out the exhaust.
Coolant temperature comes (partially) from heat in the cylinder heads.
There are also people that say things like running e85 will cool the exhaust so you don't have worry about the stock cats when supercharged.
I'm always a skeptic without data. I have heard people talk about overheating on the road course and some people chime in with 'run e85 it runs a lot cooler'. And all you seem to hear are anecdotes like "I switched to E85 and my fans don't even come on anymore..."
To add to the mix, the HP gain...
