Once the adaptive learning in the PCM adapts to the new fuel pump flow, it will still regulate the voltage properly to maintain fuel supply. Be sure to disconnect the battery to allow the PCM to reset and upon first startup, allow the car to idle about 10 minutes and then take a 10 mile drive under normal operation (don't get on it) with sever stop and go situations and the PCM will have learned the new pump.

The max horsepower is going to depend on fuel line size, proper voltage, and fuel rails and such. Having said that, Walboro has folks running up to 500hp on various applications with their 255 pumps.

Walbro lists these to be capable up to 500hp on forced induction applications. You will need a bigger injector than that with a turbo application. What size you need will depend on how much boost you plan to run.
