am also new, and using a similar setup. I have an ego twist with 2 separate PT2 minis. Had them for about a week and have alternated between the 2. Last night I got the burnt taste, read up on dry burning, took out the flavor wick, dry burned the coil on low voltage and juiced it up, replaced the flavor wick and that coil is running back to normal. So far its doing great since last night. I have read all about rebuilding my own coils and will try that as soon as I can get a tester for them. This forum has helped wonders so far just by lurking, figured I was ready to join the ranks and sign up, First post, be gentle!
For the OP, hope you got it all sorted out
