You should install the boost gauge at least temporarily to just make sure you are running 14 or less psi.
at 14psi on 93 octane you are 98+% safe. because you have the 555 injectors you may be fine up to 17psi or so, but i wouldn't really recommend it if you want to play it safe.

Putting AMS garbage, and $500 ebay wheels on a Z is like dressing a Victorias Secret model in a Walmart dress and Payless shoes. You're embarrassing yourself.
