Message power in lower gears and the reason is as follows. In lower gears, the drivetrain before the transmission has to rotationally accelerate at a faster rate than in higher gears for the same rotational acceleration of the wheels. This increases the drivetrain loss and causes lower power/torque to be put down on the ground. For the same reason, leader gears will put down marginally lower power than stock gears.

Additionally, there are several non-idealities such as irreproducibility of the run, dyno errors, and proprietory corrections that will cause the dyno reading to be different in different gears.
