Well, the turbulence only applies to the underlying pattern(s).  So what you
need to do is turbulate the pattern(s) that you want to layer on top.

#declare T_fire = texture { pigment { P_fire turbulence 0.2} }

The mapping applies to the gradient pattern, and if you want to turbulate the
mapping, then what you do is turbulate _that_ pattern, which the map applies to.

#declare Burning_Texture =
   texture {
       gradient x turbulence 0.2 ....

I'm not entirely understanding what you want to do, so I hope this helps
somewhat...
