Going try and make this simple.
I have the so called "lavatube" my friend has the OMG mod. I put a 1.5 dual coil on my lavatube and it doesn't seem to perform, it seems to stay at 4.5v even though I set it to 6. The OMG mod my friend has will actually put 6v through the same dual 1.5 carto.
So does my lavatube have some kind of safety cut-off? If I put a 2.5-3ohm dual coil in will I be able to run it at 6v and actually have an increase?
I think it's time to upgrade to the OMG soon
