lowering helps you in NO way what so ever as above stated its set that way from the factory for a reason,none of your friends are smarter then honda's engineers,an no from my experince it doesnt depend on what cams you have, name one worth a shit after market cam that makes better power then stock cams on a vtec motor with a lower vtec crossover then a type R ?

that was my same reasoning, i said why in the hell would you move the vtec cross over point on a CTR intake cam because it engages way too beautifully from the factory!!!!! even better than skunk stage 1 type r copies......

It COMPLETELY depends on the application, EVERY honda vtec motor is deifferent. There is NO magic #. Don't mean to break your heart. The best engagement point is one that is linear on a dynograph, giving you a steady endless climb in hp and tq to redline. The best engagement point won't even be noticed, it should'nt even be noticed while driving.

This was the best the engagement point with my motor has ever been. Can you tell me by looking where it's set at?

No, Peak hp always stays the same. Vtec is just there to help change the cam profile for better air/fuel. It isn't a "power-adder" However if I left it at 4700 I would have had less HP before engagement, because the motor would have been choked for air.
And it is mere co-incidence that my engagement point was adjusted to 4400 rpm, as your friends. I know you know better than that man

Im not sure what you meant by "as your friends" and the coincidence thing. 
But I don't see how lowering the vtec point helped your car... If it was allowing you better air lower, it would've brought your midrange hp up being as that your turbo is/was large, and requires a lot of flow.
I was making power all the way to my limiter on the stock motor and 6.5psi, had I been able to rev higher, it would've kept making power. Lowering VTEC IMHO is _generally_ not going to help things, especially on a stock head.
