Theres nothing to change with vvt-i. With vvtl-i you can make lift engage sooner (don't,you lose power).
In parkour, no one is afraid. One is just...apprehensive.

You cannot have controll over the vvt-i!! Thats only possible with PFC or standalone ECU. That signal is not an on-off signal like lift. Thats a continous signal to advance or to retard the intake cam timing. ( also no way you would understand how to adjust it on different conditions, Its a hard job for experts as well) Rev limiter can be changed by chrystals. Do a search and you will find the way how to. It was posted with pictures before.

VVT-i is nothing like VTEC. VVT-i changes the timing on the engine constantly, giving you fuel economy when you need it, and power when you need it. You're probably thinking of VVTL-i on the GTS. That uses two different camshaft profiles like VTEC to increase high end power, which allows the redline to be increased over the GT without losing power. VVTL-i is actually more advanced than VTEC, since it incorporates variable valve timing along with different cam profiles.
Unless you have a turbo, SC, or nitrous (and probably stiffer valve springs so you don't ram your valves into your pistons), raising the rev limiter on a GT will only lose power fast. Not worth doing, since the GT is already losing power before it gets to the limiter.
The GTS, on the other hand, still makes power at the limiter because of VVTL-i's second cam profile. Raising the limiter would still allow the engine to make decent power, and allow the driver to land in lift on every shift.
