Crower cams Vtec point

I just got the crower cams stage 2 3/4 installed and got the car dynoed. Good power, but I want to know if the vtec lower boundry should be higher than the upper boundry.
Lower boundry: 6000 84kPa
Upper Boundry: 5800 24kPa

All the other calibrations i've seen the upper boundry has always been higher.

The lower boundary is your usual VTEC point with full throttle hence the higher Kpa. The upper boundary is your VTEC point at part throttle. So for example, if your upper boundary was 6000 at 24kpa, you would engage VTEC at part throttle at 6000. What are your mods listed for the Crower cams? I have the same cams along with a comptech RH and my lower boundary VTEC point is at 4K.

Sorry it took a while to reply back to you. Completely forgot to check this forum. I will be sure to post a copy of what I have in the next day or 2. For now, I would set your upper and lower boundaries like so:

Lower Boundary: 5800 at 90kPa
Upper Boundary: 6000 at 24kPa
