I just posted a similar question yesterday. I got an eGo with the USB passthrough and the Mega Atty and whistle mouthpiece. The comments on my thread indicated that others have had this issue too. And they gave some suggestions about what to do.
Oh, and to test it, I did switch my Atty to one of my regular sized 510 Atty's (that I got with my Joye 510) and I get a ton more vapor. I can't use another Mega Atty to compare right now because I haven't got any more of them. However, I do have several on the way, so I will check to see if it's a general issue with the Mega Atty, or if it's a problem with THAT Atty.
Today, after a bit of a break in period, it's doing better, but still not so great.
Here's a link to my thread yesterday with the suggestions for a possible "fix" to the problem, if you'd like to take a look:
