Mod resistance 0.0045 Other numbers; 827.59 554.3 7.38 15.65 These are the numbers for my Hcigar, you need to run your own thermals but this should get you closer than what you're using. Try a different wire type ie: Ti, NiFe52, Ni, or if you really want SS, 430 has worked much better for me than 316l/317l.
