If you build a 1.7 ohm and use it on a mech mod, it's normal since it will heat up very slow. I'm assuming you are probably using a vw mod hence the high ohmage. In that case, you might wanna increase your voltage to increase the potential. If you are using a mech mod, try sub-ohming. I build my kayfun .7-.8ohms micro cotton (6/5 wraps of 26 gauge). My personal opinion, 10/10 vapor 10/10 flavor in kayfun standards.
