The 7th Injector Kit essentially makes it a lot safer to run the supercharger on the 5vz-fe. It eliminates any engine pinging, which could lead to severe engine damage.

The 7th injector is by no means a requirement. Yes it does make allow you to make more power but i know of multiple 3.4's with the supercharger that do not have fuel upgrades and do not have any issues. One of those is my 4Runner that is running with a 2.2 pulley and zero fuel upgrades. However, altitude does play a big part in it. If i was at sea level, i would not run a smaller pulley.
Just some food for thought.
