Based on my understanding of the system, if it's vtec that 'allows low rpm cruising' and an 'unstressed life', it doesn't matter that the high boost portion kicks in at around 3000 rpms; it's that the under 3000 rpm performance is dictated by a low lobe, low lift cam. But really, low rpm cruising seems to be possible due to a number of things, such as knock sensors, probably electric assist availability, maybe some other things - probably computer programming...
