I have a u well crown tank and using 0.5 coils with. I upgraded from the cool fire 4 to the dovpo guardian 1.5 for tc. I'm currently still using the 0.5 coils (using up old coils before I buy the nickel coils to use tc) . The tank on the cool fire didn't spit back on me. On the dovpo it's spitting juice in my mouth constantly. I'm firing at 57 watts(28 on the coolfire). Any suggestions? I've already tried turning the wattage up and it didn't seem to help.
