Yeah, at VTEC your chart shows a 24% gain in torque but the biggest gain is before VTEC kicks in. At 5500 rpm, your chart shows a 39% increase! Since FD3SNSX’s torque curve shows a hump at 5500 rpm as well, there must be some resonance in the ITBs at that point. Resonances are good (which is the whole point of the VVIS). If you put an airbox over the ITBs, you could calculate its volume to resonate and boost torque further at specific rpm. And if you inhaled cool air from outside the engine compartment while driving on the road, you could get an even denser intake charge.
