My understanding on the black-vs-red limits is this: if you crack open the VVEL heads, there's an adjustment that can be made in there. In the service manual it's noted as a VVEL "adjustment bolt". It's supposed to be a fine-tune adjustment done at the factory to set things "correctly", and you're never allowed to loosen it or touch it. They even say with a straight face in the SM, basically, "if you ever loosen this bolt, you must replace the entire VVEL assembly with a factory new one". But you could ignore the factory adjust specs and crank this adjustment out to the maximum limit it allows, which produces the larger black profile. God only knows if the ECU deals with it very well or not, or if it causes damage, etc. You'd have to ask someone who's actually done it.
