How much HP are #30 Injectors good for?

Got the car on the dyno today and I did much better then I thought but in the upper RPM's around 4,800 it started lean out. We have the fuel pressure jacked up but everytime it would still lean out up top. I know some of this had to do w/ the C&L meter being on a blow car and a 94/95 computer. Im going to get a chip burnt to correct the A/F raito up top but do you think the Injectors may be maxed out up top?

I pulled 370 RWHP @ 4,900 RPMS 425 RWTQ

You can see on the 02 curve that it starts to lean out again up top.

awesome thanks.

According to this, providing I did it right then I may need bigger injectors


Fuel Injector Max Capacity Worksheet
Injector flow rate: 30 lb/hr
Number of injectors: 8
BSFC: 0.5 ( dont know what this is so I left it the same)

Fuel Injector Max HP*: 384

I assume this wants you to enter your HP in Engine not RWHP ( which I did ) so it comes out to 425 FWHP and according to this the 30's would only handle 384 FWHP
