Perhaps it's a straightforward matter of triumph over adversity, with the tale adhering strictly to the rule so memorably spelt out in Tropic Thunder: "Never go fullretard."
Had the CAM been held at full advance instead of fullretard for this dyno, torque would have remained at the blue line at low RPMs, but dropped short of the blue line at high RPMs.
The variable intake timing gained 10% more torque across more the lower half of the rev range until the VVT reaches fullretard at 6000rpm (which is where the blue line meets the red line).
