So I was tinkering around with my Aspire Bdc tanks trying to get better vapor production/air flow and I figured it out! First I tried drilling out the side air holes on the 510 connector it didn't seem to do too much but did improve. Then I took out the coil itself and took the bottom connector pin out that holds in the positive coil leads and drilled it out a little more with a 1/16 bit and wow substantial difference!
