a k03 hits peak boost by the time you step on that pedal, but your engine is still only spinning at 2k rpm and not making that much power, but when you hit 3 and 4k your now making more power so i guess that's when you people "feel something kick in"

if i had a video camera i would show you my boost gauge hitting peak boost almost immeadiately. i'll ask my friend later if he's got one and post the vid
