watcher64, What preheat, punch and limit do you use? I've been struggling to fine tune TC with Ti be cause nickel (prebuilt coils and self wrapped both) offer me no flavor at all. I'm currently running Ti1 22g 10 wraps 2.4ID @.1ohm. It's a dual coil on an Alliance RDA. I am using the steam engine Ti Grade1 profile. I built it on my FW upgraded IPV4 and was getting good production with okay flavor between 75-100J at anywhere from 350-420°F. Translating that into DNA speak is where I'm failing miserably. I know the device is capable I just don't how to get it to that point.
