Remove the restrictor and re-test. Let me know the result. Also set the PI-R to Fully clockwise.

You can also increase the pump pressure (1/16" allen screw at front end of the pump head) to 180-190psi. (about 1/2 turn clockwise).

So I can use 1.0 Check Valve Jet!
Use You said method?
If 1.0 Check Valve Jet on 180-190psi pump I can get how much cc?:)

I would check the flow curve on the user manual. Take 15psi off for CVJ.
So.. what is the flow rate of the 1mm jet without the restrictor?

PI-R is set by user according to their preference.
Spray by Boost only ........ PI-R fully counter clockwise
Spray by IDC only ........... PI-R full clockwise
50/50 ........... PI-R at 12 pm.
Most of the time leave it at 12pm. You really need to go to a specific forum to ask the members. We only provide the system but do not know how to tune the car with it.
