Clearomizer for ipv4s

[MHz225]

Hey guys
I need help finding af clearomizer for my ipv4s, i bought it a few months ago and bought the KangerTech Subtank mini along with it.
It worked fine for a few days before i started getting this burnt taste..
I thought something was wrong with the burger so i changed it, but it was the same.
I can still use it without the burnt taste if i keep it under 15w but then the ipv4s is a complete waste.
Is it a wrong clearomizer or what?

What coils are you using with your subtank mini? Are you using temp control or power mode?
