This is all great reading, thanks for posting.
Do you think we could take a step back, though, and cover some basics of tuning? What's the difference between street tuning and dyno tuning? What are some general procedures you go through in each process?
So far the only two things I've really understood are:
VTEC engagement (when you have a vtec motor) is best determined on the dyno... make a pull with a high engagement point and then do the same with a low engagement point. Overlay the 2 torque curves and set the engagement at the point where they cross.

When Vtec is engaging you SHOULD NOT FEEL IT!!!!!!!!!!
It should be a smooth transaction to high cam, if you feel vtec that means its engaging too late and you could have been making more power before it engaged...you would think that having vtec engage should throw you a whiplash it shouldn't.. your losing power..
Good day sirs
