Don't go bigger than you need to or you may have problems when you go up on injector and try and turn it up.
x2...I had to stretch the spring in my RJC controller to get my 44 back to 20 psi and above after just mildly porting the hole. I can get it down to 13psi now even with an HD actuator and boost at 20+ psi is rock steady. The 44 is way easier to control though I suppose but I had issues before porting it.
