I had googled my problem before I posted here - as Google didn't help. As you may or may not know. I have an iTaste VTR with an Aerotank. Now, I keep getting burnt hits. I tried lowering the voltage to 5 (the max is 6) and it helped a bit, I got a burnt hit less. Then, I figured, what the hell. I lowered it to 4.5 and it's fine. The wattage is on 13 now. What's the highest the both can go without get a burnt hit?
