    215hp is about 6-7 psi
    255hp is about 10psi
    300hp is about 15psi and about the max for pump fuel
    350hp is about 20psi
    with the correct tune the 1500 can run a long time @20psi

    You can run more than 20 on pump people do it all the time

    there comes a point on pump fuel when you have to retard the timing so much to run X boost
    that you can actually make more HP at a lower boost and higher timing

    I have never seen any Doo charger do a real 20psi
    also I have been out of the loop on new wheels

    I'm mostly talking about the turbo guys.
