I have my Aspire nautilus on my iTaste MVP 2.0 at 11 watts, running a 1.6ohm coil. I have also used it on my Nemesis mech mod with either an LG HE2 or a Sony VTC5 (I already know that mech's aren't ideal for tanks, but it was working really great). Everything has been fine, but now I'm noticing a bit of gurgling. Am I just under-powering the coil?
