Meant to type NOT just one setting. 4500 is a waste of time and effort and money.

I can reassure all that VTEC @ 4000RPM-ish works well on the NA setup with a test-pipe and really does add nice power in mid-range. This is with fuel tuning alone, no ignition adjustment.

4500 sounds right to me. Why would it cost any more effort or money to tune VTEC to 4500 or wherever a guy wants it as opposed to 3600? Lol

P.S. final result still depends on my tuners advice when we cruise tune

Sounds good. I'll be supercharged eventually so a retune will take place then. For now, NA +++ babeh
