There are other ways to get around this if you absolutely need it to be faster.

In 2014, we ended up using two solenoid valves to speed up the lift on our intake which was raised by two pneumatic cylinders. It is possible that we were using solenoid valves with M4 fittings, which only allow about 40% of the airflow of the permitted 1/8" NPT. In any case, I don't recall seeing a rule which specifies the maximum airflow of a pressure regulator.

Getting 2 solenoids to fire 2 actuators at the same speed is tricky unless you use flow controls (Which I Highly recommend).

If the regulator is your bottle neck, this is an easy fix.
We didn't have a problem with timing or speed, but this was a cRIO robot, which (IIRC) supported splitting the signal from the solenoid breakout to two solenoid valves. In any case, a spike is still a legal solution to drive multiple solenoid valves per R53.
