***I guess every car out there runs stock fuel pressure too?***

No, there is a rule .b. p 5 any fuel pump may be used. & an external fuel pressure may be installed.

Nothing personal , but I have seen too many of the rules threads you get into get way out of hand. This is a tech thread for Mazda and you can use the info as you see fit. If you disagee--fine--I will agree to disagree. Just wanted to clear up my first post and the meaning. I was trying to help someone with information--feel free to pick away. Do you think there is a specific rule to allow valve adjustment?
