As others have stated it's a good place to start.
As for a larger nozzle. You are spraying into a 3 inch pipe. From what I have seen I would not go over a m5 in any piping under 3.5 inches. If you need more than a m5 can provide than add a second nozzle. Start with a m2 as the second. Keep them a min of 3 inches apart.
Also the bigger you make the hole (larger nozzle/ extra nozzle) the higher your on-set duty cycle is going to have to be.
Good Luck
the charge pipe i have is 2.5 inch. i know my tune is a little off, i figured. i had a pretty good afr at redline (11.5)
i mean the knocl comes in at about 4300 rpms, a little after the turbos spools up
