just what the title says my ohms have been jumping around on pretty much every build ive made. cant seem to find a solution. i have a brand new xpro m80 plus 80 with a mutation x v3. im thinking it is a problem with my rda. i have made sure to tighten my screws down but no matter how tight they my ohms are still jumping. havent had any dry hits. i am pretty new to building so any advice for a newbie will be appreciated.
