Fueling & Injection - Stock fuel pump limits?

Ok I went and talk to my tuner today and he said I should upgrade my fuel pump? My set up is lq4 with ported and polished heads with a mild to large cam can't remember exact specs right now sorry and ls3 intake and injectors. I'm expecting 450-500 who hopefully Do you guys think the stock fuel pump will support this set up?

I would think at 450 you would be maxing the stock pump, and for sure would at 500 rwhp.

You should be able to go with a single walbro/racetronix pump and a hot wire kit

now if i get the race tronix pump would i have to get the hot wire kit or could i get away with just the pump?

You should be good with just the pump.
I plan on upgrading in the near future but I'm currently running the Racetronix Pump only with no problems on my current set-up.
