If you are only interested in your max rate of fire and lowering the dwell then you could remove the insert from the rear fring can. Remember that this will lower your input pressure and you will start to get drop off.
The Un1tec rear can is one upgrade you might want to consider as this has a larger volume than the standard can.
Other things to consider- What is your board capped at? Dont run your Epiphany at its minimum dwell. Put it up until it cycles fully then put it up another 5. Your gun will require a lot more maintenance if your going to run it at 30bps!
Personally i'd install the QEV set the dwell like i said and enjoy shooting well at 15bps
