Hey dude,
I got a vap recently too, and well the temperature is gonna burn different toxins so it's quite important. Although I'm no expert, what I found from a little research is that over 400 you're starting to burn more than just thc, so I personally keep it around 390 but its really a personnal prefference thing. A lot of peeps seem to burn it lower than that though, so test it out and find your magic spot!
