just set the vtec changeover to 4700rpm and set your fuel settings to aroun -5% bottom and top end, and taper it up to -2%for midrange and leave it at 0 at 4700rpm....it will help gas mileag a bit, won't hurt anything and a leaner mixture makes more power....but really, it's not enough of a change to make a big difference....and yes, changing the vtec changeover point is helpful..it's too high in stock form....power is already falling off when it changes over.....and the h22a's run too rich anyway

can't remember, but the top one is 4700 and the other one can ONLY BE LOWER.....low to high is 4700rpm and high to low should be 4600rpm or whatever you want...it's just when the cam goes from high to low during deceleration.....not a big issue.....uses less gas on the low cam, so i set it to 100rpm lower than the other one
