^^ Same rule does apply. No Vtec until the Engine has warmed up.

What gear did you do these pulls in? Your AF ratio sounds really rich. It should not be at 10.1 the whole time. Should be closer to 11.8-12.0 under boost. That rich of a AF ratio will lead to less power. The Comptech ACM is what controls the fuel under boost. The shop you went to for the dyno is actually pretty well known in the RSX world, were they able to confirm that vtec wasn't engaging until 5K RPMs?

I agree that your numbers should be higher. Have you ever dynoed somewhere else? Numbers to vary from dyno to dyno.
