Nothing.

You dont need to do anything.

If anything add like 1% fuel across the board but thats it.

the 550CC injectors will work correctly with the Z32 mafs for the most part, as the 550CC injectors and Z32 mafs are equally larger than stock,

however if you want to do it by inputting the MAFS into the S-AFC and tuning for injectors (will do the exact same thing)

check the s-afc book on [apexi-usa.com](http://apexi-usa.com) for 300ZX twin turbo as your mafs IN and the Sr20 that you have (im assuming S13) as OUT

then take out 33% fuel across the board
