Narrative:

When preflting the aircraft, at cae, I noticed an exceedence (on exceed page) on both engines in excess of 120% torque. After discussions with maintenance personnel, was told this was due to a computer glitch that these were recorded. I also called the captain from the previous evening and he concurred these parameters were in error. Upon arrival in pit, maintenance grounded the aircraft because 'the computer doesn't lie, so the over-torque did indeed happen.'
