I have 2 Velocity's , I have run them in TC using Ti 26ga dual coil, excellent flavor. But I am shying away from TC for now.
Now have a Dual NiChrome80 26Ga 3mm 10 Wrap at .5ohm using Organic Cotton.
Make sure you are using enough cotton.
Some people say it should be a loose fit and slide back and forth with some tension.
I don't I make sure I get it tight enough to pass through when I twist the cotton, then untwist it
when I have it through. when I pull on it, it should be pretty tight fit.
I also put a little cotton on the deck, just enough to hold a little juice and make contact with the cotton running through the coils, under the coil, make sure there is a good clearance that runs under the coil and that it is clear of obstructions all the way around.
I see a lot of people try to pack the cotton in so that the coil rests on it. This has never worked for me. You want max air flow all the way around that coil.
If I can post pictures I will, just don't have time to right now.
On an iTaste MVP3.0 (30w) running at 30W. and an IPV 3 Li VR running it at around 32W to 40W.
I get good flavor, with a loose draw, about 3 or 4 full turns from fully closed AF Control.
All Indirect holes open as well, on both Mods, but the 32W to 40W is better.
But, you also have to make sure the coils are in the correct location.
If they are too high/low off the deck or too close to the air holes, that can be bad.
I get them about as close to the posts I can, and right in the middle of the screw holes.
Try lowering or raising the coil/coils. If dual coil make sure they are both firing equally.
One last trick for real good flavor off the Velocity.
Take a 510 drip tip with o-ring still on, Should fit perfectly in the screwed on drip tip,
not the adapter, although you might be able to use the adapter and get same/similar results. But try this first.
Only issue is that the Drip tip will fall out, it's not a fully snug fit.
What this does is concentrate the vapor into a stream, and it doesn't affect the airflow too much, a little, but not bad.
Also, make sure you don't have a case of Vapors Tongue.
Its a 1:1 for sure.
