Faulty torque limiter or what?

The question is about Fiat Stilo 1.9 JTD 8V 115hp, EDC15C7. The same ECU is used in some early Alfas models, so hope I'll not angry some people.
I made a log on 4th gear and noticed something I can't explain to myself.

"Time" "Engine speed" "Total fuel quantity" "Intake air quantity" "Boost pressure" "TAG"
"sec" "rpm" "mg/i" "mg/i" "mBar" " "
.
44.35 2029.0000 59.7000 787.0000 2092.0000 ""
.
At about 2000-2300rpm, the fuel is 59 mm^3!!!
Torque limiter should restrict on 54 mm^3 and smoke limiter at about 55 mm^3. The Rpms above 2500 seems to be OK.
Can I trust on readings of Multiecuscan?
Can somebody explain how it's possible to have more fuel than TL allows?

Regards!

This is normal... The diagnostics are correct, actual injection is higher than TL. Reason is pilot injection.

I thought the torque limiter is applied to the whole fuel quantity, including pilot injection. Or I am wrong?
