ya put your recharge to zero, but since all you're looking for is max bps, you should also set your dwell to the lowest dwell where the gun will still cycle. here's another link to a different page on zdspb that details it. http://www.zdspb.com/tech/mguide/sho...ectronics.html
and this is the how to do it part:
(with the gun aired up...)
1. Lower the dwell to the minimum setting (or an extremely low setting, such as 12 chirps or 6 milliseconds).
2. Gradually increase dwell until the marker begins to fully cycle. You will know this time because, when the marker has trouble cycling, the sound of the bolt firing will be muffled and sound erratic, denoting inconsistencies. When you reach the point where it fully cycles, the marker will sound loud on each shot fired, with minimal sound difference between the shots (inconsistencies can be caused by other things, such as the reg, please note).
3. Once the Shocker is fully cycling, increase the dwell another 8-12 chirps (2-3 milliseconds), and that will be your dwell setting.
a good starting point for the lowest dwell is around 11-12 milliseconds (35 chirps) unless you have a sprung/aftermarket bolt kit
