So I upgraded from a CF4 to an MVP 3 Pro. Max W on the pro is 60w. I was using the classic ISUB apex .5ohm coils at 35w and it was fine but i wanted more. So I purchased the Isub Apex 5 Tank with BVC clapton .5 Ohm Coils. The wattage on the coils is 35-70. I primed the coil correctly and vape it at 60 (the max for my mod) I get little to no vapor and many many dry hits. What gives? Ive checked the connections 10+ times and everything is in place correctly.
