Yeah something seems off......
I also get way different values using MAF vs using torque from the logs converted to HP using RPM. I tried a few points.

6000rpm, i get 460hp from torque and 412 from MAF (using 1.25 for crank HP)

5000rpm i get 401hp from torque and 365 from MAF (using 1.25)

Not sure exactly what the torque parameter in the log is measuring (or how it is measuring), but wonder if it might be affected by torque converter or something.

Either way the MAF conversion seems more accurate.
