Well here's an update. It got way worse. When I first got it, I was vaping 4.3v with no problems, no burnt taste, no popping coils, nothing.
Now, I can't vape above 3.8v or I get the burnt taste, and now I'm popping coils. I absolutely cannot be the only one who can't run a 2.5ohm coil at 4v+. This sucks because 3.6-3.8 gives me no throat hit, and vapor production is almost nonexistent.
Honestly, I had it at 3.0v last night. It's lowest setting, and lower than most egos go. It popped a damn 2.5ohm coil. That, to me, still makes me think it's firing WAY higher than it should be.
All this is seriously baffling me. My MVP 2 that I ordered on Monday should be here in about an hour when my mail comes. If that fires everything like my ego does, I'll be happy (since these came setups are still working fine when transferring straight from the vamo)
I also think it's the Vamo. But, and I really don't think this is going to make any difference but I can't think of anything else, have you tried another topper on the Vamo?
