Si es en una impulse esto te sirve

Here's a short cut way to get an Impulse with an LPR up and running close to "perfect" settings.
Set your Impulses operating pressure to 150psi.
Set the LPR at its maximum output pressure setting. This will be 150psi. We don't really care about the LPR's actual pressure. We are trying to do this the simple way.
With the operating pressure at 150psi, adjust your dwell to get the gun to shoot about 300fps. This will give you a very good dwell setting to use with the LPR.
Now set the operating pressure up to 200psi.
Shoot over a chrono, adjust the LPR to get the velocity you want, lets say 290fps for an example.
There you are done!
To change your velocity, adjust the LPR. Leave your dwell and operating pressure set as is.
Now you can tweak all these settings to "fine tune" your Impulse but this gives you a great starting point that you can fall back to if all gets messed up.
NOTE: Some people prefer to use the technique above and then use the max-flow to adjust the operating pressure and therefore change the velocity. Neither way is wrong, it's all just personal preference.
