I was boned up on these headers until I read the initial dyno results. Then I just gave up on the thread..as it wandered away..
Well designed headers will make power - in 2/4 barrel carbureted engine you may need to re-jet and/or play with the timing - but with our ECU, headers should make instant power. The ECU will adjust the injector pulse to compensate for the A/F ratio (rich or lean) and advance or retard the timing.
