I have a 94 vtec prelude and i was woundering what i should set the vtec at?

 

The most accurate way to set your VTEC is putting it on a dyno. This has been discussed TONS of times. The tuner will look at your power curve and set the VTEC to ingage where he/she feels the lower cam lobes starts to not make power. That way the higher cam lobes will take over from there. Giving you power gains and acceleration throughout the entire RPM range. Fuel settings will also be adjusted accordanly.
