Most times people use an NPAS, however this can be accomplished by increasing the size (not tension) of the valve sping.... Wait just realized that's for an open bolt nozzle. I'll have to look at the brass tube nozzle and let you know. Basically you want the valve in the nozzle to close faster, putting less air in the barrel. A different spring that moves the seal/plate closer to the nozzle is what you'd want. I just can't remember where the spring is located
