    '00 Sierra, MP78mm, NP turbo headers

    '00 Sierra, 408, MP78mm, NP turbo headers, 12psi, pump gas.

    Holds boost nice and steady. Doesn't peak early or fall short on the topend.

    Max power was 760hp/759tq when it was cool. I'll post that graph later.

    a little fine tuning and 14psi resulted in 804hp/754tq

    i think i'm gonna quit there; 800hp was in the back of my head as a goal to reach.
    Being that the setup is on pump gas and meth i'm sure there's more power with more boost as always, but i think it's enough to run strong at the track.
