Benchmark the MAP sensor first before attempting to compare WOT. When datalogging, I first record all sensors with ignition ON but motor OFF. That will give you MAP reading at atmosphere. Its not always 100kPa. MAP will fluctuate at WOT and be at its highest point at torque peak, for instance, 5300-5500rpm for my motor.
