I've read guys with the 19 model running both those weights. They talk about it in the racing threads. Ask @GTIfan99 about it. He has a 19.
Price and availabilityIf your driving on the street and your oil temps are staying below 240-250, just use the 0w-20. Why wouldn't you?
I am not sure but it does. Pretty common phenomenon.why would a tune make the engine run cooler?
The general consensus about not hammering your car until the oil temps are "warmed up" is probably good advice. However, I typically turn my car on and drive it off without any waiting. I have to get on the gas to leave my neighborhood but just do so without going full send, as usual, there is no quantitative data to support most of the advice given w/r to oil and so much of it is car guy folklore. Oil is flowing fine when you start your car unless it's incredibly cold (well below zero) so that would be ok for most folks responding here. Aftermarket tunes...no idea on that one but I have heard this repeated here. Finally, 0W vs. 5W. Assuming the same approval (VW502 00), 2 oils one 0W and one 5W ("W" = "winter") will be the same - the lower winter rating would only impact you if it was incredbily cold out and in that case, the 0W would be the better choice but in the typical temps most of us see - they are both 40 weight oils and can be interchanged with no perceieveable difference.
This is all handled with some technical background here with some searching:

also buy in spring that $26 will be $16 after rebate.
EQT and Sneeky must have made adjustments to when the thermostat opens because both of their tunes run 10-15* cooler. Coolant and oil.why would a tune make the engine run cooler?

I’m EQT protuned and my temp is usually around 218
My daily oil temps are "normal" as far as I know with Uni's software - 210-220 varying on ambients and how hard the car is being drivien/RPM. At the track in cool weather I have seen 240+ and the same beating on it in the mountains. Those temps are well within the range that modern oils can handle without drama.And again, I don't see that as a positive. My oil temps are staying 190 to 200 in daily driving with my EQT tune. I actually want my oil temps to be 210 to 220 to burn off condensation, properly lubricate, and maintain proper fuel efficiency when just driving around town.
On track, those targets do nothing to reduce temps.
I 100% fail to understand EQT and Sneeky's reasoning in doing this, other than marketing to people that don't understand that they actually need 210 to 220 oil temps and that lower targets won't help them when pushing the car hard.
Hell, why not just remove your thermostat? Car will run cooler on average. Cold engines are cool. Everyone is doing it. It's adds 11ty hp. If CAI are the bestest, wait until you run cold oil. Watch out Hellcats.
