A bit higher PG in your juice, say 60/40 might help. You can also try a higher nic concentration, but do be careful as typically the more vapor you make with subohm use results in more of a hit of nic. Easy to overdo it, and why most folks lower the nic concentration of their juice for subohm vaping. But generally you're not going to get as big a throat hit as you would with a MTL high PG high nic setup.
