What would happen if you lowered the vtec point?

If Honda has correctly identified the rpm at which the curves cross (and I don't see why they wouldn't have), then you will lose power by changing the VTEC kick-in point.
It's possible that other engine mods may affect the crossover rpm, in which case changing the VTEC kick-in point could be beneficial.

changing engine settings of S2000 sounds awfully stupid as much as people putting springs just to make the car look dropped and cool.
Honda engineers spents endless hours and millions of dollars to produce this one of a kinda car, why temper with it?
Unless your car is being used for competition racings, for everday use and drivers, no need for all these modifications. If anything, you will ruine your car with your genius plans.
Leave it alone!

With a VAFC, many people have successfully lowered VTEC engagement to 5500rpm. Intead of the big jump around 6000rpm, it ramps up smoothly. So it gives you an extra 500 rpm of highter torque. Most reports I've heard say that lowering it further, however, causes the engine to stumble at those lower RPMs. I've heard ONE report of somebody lowering it to 5000 and increasing the fuel trim and getting great results, but I've never heard of anybody else saying this, nor was a dyno chart published.
