you want to rev past your peak power so that you stay well inside the high cam kickin point.
I.e. i make peak around 7600, but rev to 8500 and drops back to ~6200rpm on gearchanges.
my recipe:
sr20ve
n1 cams and BC valve springs
2.5" exhaust
xforce headers
generic pod filter
nistune ecu daughterboard
