Right Dino.

Interestingly, this very topic was discussed to some length in the latest Sport Compact Car regarding turbo sizing. Again as stated there, the temperature of the boosted air from larger turbos creating a denser, cooler charge creates more power. Sort of the same concept with intercoolers or a cold winter day.

But 15 psi is the same whether it come from a T25 or a 25g. It's all the same.
