damn, you've likely already lost power with your current combo. a 70mm throttle body is way too big for what you're running. FYI, i'm running a gt40 intake, and gt40p heads, and a 70 is too big for that application.
you're on the right road with all your intake and exhaust mods, match that 70mm up with a set of alum heads and a cam. If not, lose the 70mm throttle body for a stocker.
