Welcome to ECF, tyjo...
To answer your first question... no, none that I'm aware of. As to your second question... there are things you can try.
1. Insulation. A "mod cozy" made of insulative material... that will hold in the existing heat generated, to a higher temp.
2. Resistance. Lower resistance and/or a higher application (regulated mod?) of current will produce a higher heat flux.
3. Physical size of the atomizer in question. You say it's a "tank", but not specifically what tank. A smaller tank, or one keeping the liquid closer to the atomization chamber / coils will serve to heat the surrounding liquid to a higher temperature.
4. Reduce the inlet, fresh air flow... assuming your "tank" has an AFC. This does two things... the lesser is it reduces the amount of ambient (cold) air drawn into the atty.
More importantly, it applies a higher percentage of your draw vacuum to pulling juice into the atty. All
"pressure differential" atomizers with AFC can be tuned this way.
