An how does boost relate to power?? The guys at pro charger and my tuner have my spec and that is the pulley pro charger recommended with my spec.. not me. Everyone in this forum is so stuck on "X" power means you need the LT4 fuel system and when every LT1 will run out of fuel is static. It's all relative.. I agree though, it's very possible I could need more fuel. Especially given the LT4 stock cam has an increased fuel lobe and .2mm larger pump. We will see how it goes. I don't have much faith in the amount of extra output the LT4 pump has in comparison to the LT1.
