Has anyone ever lowered their VTEC threshold?

I've noticed on my Ktuner that I have the option to lower the threshold at which VTEC kicks in. I believe that factory is set at 5500 which is only 1k before redline. Has anyone modified this setting before? I don't see how lowering it to say 4500 could hurt but I thought I'd ask if anyone had prior experience. Thanks.

If lowering the VTEC threshold, the fuel trim needs adjustment too.
I'm not sure about the newest cars, but older Honda's were open Loop in VTEC (O2 sensor not adjusting mixture).

Honest question: What are you hoping to achieve by lowering the threshold?

I was hoping to achieve an answer to my question--has anyone tried this and what were the results? Unintended consequences? Experience only, no conjecture.
