Sc with a3.125 pulley and around 10lb of boost. his hp numbers seem good but He is running really rich up top.
He is running stock injectors with a 8:1 fuel disk

nothing's wrong and looking good to me. the hp curve was a bit flat near 6000 rpm. that may be caused by the excessive fuel from running rich. looks like a manual 4th gen with MEVI.
I dont think running rich is a problem here and his car is still on the safe side. How rich is he running? Do you have his AFR curve? You can tune the car with SAFC or just spend 25 dollars for a needle bleeder valve for the FMU. I would suggest to lower the fuel pressure first then fine tune it with SAFC.
with 8:1 and 10 psi of boost, the only thing that will concern me is the super high fuel pressure that's flowing thru the injector. (my guess is about 100psi of fuel) Since he's 4th gen, he can always switch to 370cc injectors from 300ZXTT. yup...they have all the toys they need and you dont see any boosted 3.0 5th gen go above 400whp.
FYI: Mine was running hella rich before and then it was running super lean. 10psi, 2.87pulley, auto tranny.
