The only ways I can think of to get the DynoJet to produce false high graphs would be to lighten the drums on an inertia model (which it is very unlikely anyone would do), or to artificially heat up the dyno's temp sensor so that it causes a higher air temperature correction (which would only work when displaying corrected graphs, but not when displaying uncorrected graphs).

Although, producing a fake DynoJet graph does not need to be done at the dyno itself. People will simply use image editing software.

Such as was done, poorly, to this one you posted. (Incorrect font on the vertical HP scale. Incorrect font and alignment on the power and torque peak values. Most cringe worthy: peak values do not match the graphs. Graph shows the torque exceeding 330, yet the peak value says 324. Graph shows the HP exceeding 370, reaching about 380, yet the peak value says 368.) This was a poorly executed dyno graph edit.
