Hey guys just got my 510 mega kit from madvapes.com and I've been really impressed with the battery life. But I have been using Johnson Creek juice; Tennessee Cured and Summer Peach at 24mg (high nicotine). On my DSE 801 the taste and vapor is great! but i haven't had the same luck with the 510 and I believe it to be my mouthpiece. So using a swap (not really a mod) i have gotten much better production and throat hit.
Here are the instructions.
Step 1: Take the 510 Mouth Piece off.
Step 2: Get out your dse 801 soft rubber tip. (MUST BE SOFT/RUBBER WILL NOT WORK WITH THE HARD CAPS WHICH COME WITH THE CARTOMIZERS!)
Step 3: gently wiggle the dse 801 mouthpiece over the edges of the 510.
Step 4: Drip and Vape!
