stock injector limits?

Is 245 rwhp. within the limits of the stock 19lb. injectors or should I step up to 24lb injectors?

You can keep the stock injectors for now. My 5.0 put down 244rwhp and that's through a power-sucking automatic tranny with a stock torque converter, and I'm still using stock injectors but with the fuel pressure raised to 45psi.
