We're talkin' Weber DCOs here... the fuel map just says "Here be dragons" in a lotta places *^)

The green line is how I had it tuned by butt-o-meter. The red line is how it ended up after ~$800 worth of brass was cycled through the carbs. The midrange just doesn't respond, so there's a physical problem, and the exhaust is 95% sure to be it.

Falling on its face at the high end is ignition. Turns out the Lumenition Optronic system is accurate but simply can't supply enough current to keep the sparks from snuffing out under that much load. Correcting this is my next project, then I'll revisit the exhaust thing.
