I followed Mooby's video on how to setup the PTB mod, Problem I am having is I am getting a very small amount of vapor. A 6 second drag gives me paltry vape, mind you this is with a 510 fully charged and I cleaned the atty with tissue and air duster to removed sludged up juice in the atty res. Anyhow, if anyone has some helpful tips as to how I can get some more vapor from the 510 with a PTB mod please reply.
