have you inspected the accelerator pedal assembly? is it loose, or is the wire connector solidly in place?

the drops aren't equal, or consistent within each full-throttle event, which would mean that there's a dead spot in the accelerator travel. it seems to indicate a loose-something than a bad component.

it could also have to do with the g-forces you're experiencing on those right-handers, and pushing the pedal at an odd angle.

it might be worth logging at a standstill while physically playing with the pedal -- put a side load on it at 100% throttle, or wiggle the electrical connector under the same circumstance.
