I seem to remember a nice illustrative post on setting up / tuning a Kraken. Can't seem to find it...
In particular, I seem to have a little over enthusiastic venturi effect taking place. At times when I inhale deeply or quickly change to an exhale in a breathing cycle, it seems to "stick open", and at my pause of breath or quick change of cycle, the gas is "racing" out the exhaust side from the supply...
It could just be me needing to learn to dive it better, but I want to read some to see if the tune (factory) might be just a bit aggressive....
Love this regulator!!
