Tuning Benjamin Discovery at 3000 psi

For anyone that moded the Discovery to safely handle 3000 psi, a few questions.

1. What better valve screws did you use?

2. What shot count did you achieve? Better than at 2000 psi?

3. Any other advantages did you attain by going to 3000 psi.

Don't need to do this, just wondering what advantages of 3000 psi in Discovery. I have several other 3000 psi guns so I would probably never mod the Discovery for 3000 psi, just interested in what others found when they did the 3000 psi mod?
