I have the X-Pro m80 plus that i am running an Atlantis 2 with a .3 ohm coil on. it worked fine for about the first week that i used the tank on it, but recently whenever I fire it at 30w (my normal wattage), the mod will read it at 1.0+ ohms and cause the voltage to go up quite a bit and get hot really fast until i tap the fire button a couple times until it goes back to reading .3. Is this a normal thing with these types of mods or is it something that i should be worried about?
