Nick, actually the first main butterfly is always partially open. the 2nd one opens at 4400? and vtec engages afterwards at like 5400 or something. I can't recall right now.
yeah your right but the partially open one opens fully at 4400 then the next one at 5800 or 6000 or some shit. but anyone who has a gs-r knows that something happens at 6k. or around there.
