If you're talking about a cartomizer tank, I don't know of a tube that comes with one. Huge clouds are the result of more than one factor. The voltage, the resistance of the atomizer and the VG/PG mix of the juice all play a part. Actually the ambient temperature is a factor too.
My best recommendation for you would be a buzz pro along with an M1A1 tank. They are both available from notcigs and the tank is sold in colors that match the buzz. However, that's a Cadillac mod and it has a Cadillac price. So, I can't be sure that's what you're looking for.
The
mods discussion section of the forum might give you some more ideas.
