TFV4 coils can be very temperamental. Have a look and see if the cotton is well soaked. If not, drip directly on to it and see if that improves things.
75 watt TFV4 is not what is described as a MTL vape.
You would probably be better with a Kayfun (rebuildable) or Nautalis (stock coil) down in the teen watts for your style of vape.
In honesty you would probably get more 'clouds' also.
