vx - lean burn vs vtec-e?

you guys talked me into it, now you're in for it. thus begins my merciless assault of noob vx questions! just kidding, i'm not totally helpless. just unfamiliar with the car right now.

i have a basic understanding of vtec and vtec-e but what i'm wondering is, can vx owners feel the vtec-e kick in around 2500 rpm? i notice it, or something similar, in my car very clearly. when accelerating, between 2500-2700 rpm i notice a sudden and distinct increase in power. i read on wikipedia that 2500 rpm is the vtec-e switchover so i figure that that is most likely what i am feeling. can someone confirm or deny this?

my next related question is, when people talk about the vx switching in and out of lean burn, what exactly do they mean? is that just another term for what vtec-e does, and if that's the case, is anything under 2500 rpm considered lean burn since (basically) only one intake valve is opening? or is lean burn something else altogether? if it's something else, how does it work and how do you know if/when it switches on or off?

thanks in advance, everyone.
