Wastegate Theory
Ok.. perhaps I'm overthinking this or just going about this wrong, but any people who can add to this please do.
Ok.. so I see alot of people on here once they do the built motor and more boost setup, they go to a larger wastegate (40mm+). I don't understand the need for a larger wastegate I guess. If the wastegate is designed to let out excess exhaust pressure and regulate boost levels, when you are at a higher boost level, then there should be less exhaust needing to be let out by the wastegate. So if this is true, why run a bigger wastegate when there is actually less stuff being flowed through the opening at full boost and therefore no need for the bigger opening?

that about sums it up, just able to relieve exhaust faster
