How to lower pressure?

[Mr. Nasty Dan]

I wanna know how i can lower operating pressure just for sake of knowing. Like get less air efficency but lower pressure.

volumizer. but that will give you more air efficiency and lower pressure... i think thats what you meant

You'll also need to adjust your LPR pressure. That's all the crap with adding and removing shims... but a voluimizer/maximizer is definately the place to start. There's another thread somewhere telling you how to fine tune your LPR and dwell. Just search around.

The only way to lower your pressure is to add a volumizer. Just remember it has to be a Speed/4 specific one due to the length of the threads.

lol, i actually did mean to make less shots per tank and lower pressure, i have a 4500psi so i can do this. So having a stock speed, what should i do, maybe i should of rephrased it, sorry. So...

The only way right now to lower the operating pressure of a Speed is by increasing the valve chamber volume by adding a volumizer.
