There's measured torque (as in direct measurement from the dyno) and then derived torque (which is a calculated value based on estimated engine rpm).

Here's the dyno chart:



Max for derived torque (to compare to your brochure figure) is ~253Nm @ 2,300 RPM. Though if you look at your brochure figure it states peak torque as 280Nm @ 1,700 RPM which clearly it wasn't making. Reason for this is probably due to torque limiters in the transmission not transferring full torque until higher up in the rev range. So torque is good but really hard to compare anything back to manufacturer specs which are flywheel figures without any transmission or driveline losses. Dyno figures are measured at the wheels so it makes it hard to make any direct comparison.

Unfortunately I didn't ever have a stock dyno chart for my old 125TSI for comparison.
