Without seeing a datalog and your calibration it's hard to say, but sounds like a faulty TPS sensor.

TPS to MAP relationship looks normal. Where in the datalog is the problem?

What exactly is the problem?

Where in the datalog does it show the problem?

That looks normal - the TPS drops, and the MAP also drops, which shows the throttle plate changed.

I do see the TPS faulting at 3:26.95, where it drops out briefly.
