Does anyone know what the limits are on the stock pwm fuel pump controller in our machines?

I'm talking maximum current throughput at 100% pwm duty cycle, or max wattage rating etc?

I'm dropping in a GM 65psi 250 lph fuel pump assembly from a Camaro Zl1 on my swap and just want to make sure the stock controller is up to the task.

I haven't tested the pump for current as my meter only goes to 10 amps and don't want to risk it but from what I'm seeing online it looks like the pump should be somewhere around 16-17 amps max at 13.5v.
