That is one Fancy Cartomizer setup 
Could be the Coil or the applied power or your liquids of choice. I have noticed differences in Flavor perception on every style Pre-built tank I have ever used. Same flavor has taste differences on every single one. Some good, some okay and some - just plain nasty.
Once I started building. I found Most better designed tanks will give similar results.(Most, not all) Same with rda's
I'd suggest passing this unit along to someone in need and purchasing something with more flexibility.
Best of luck
