Ok, being a hybrid like that it isn't really apples/apples to compare to the stock curves.

That said, the 56 235 has a peak of 210ft-lbs (2100rpm) and 140hp (4200rpm) according to the Vehicle Information Kit.

The 61 261 was 218ft-lbs (2000rpm) and 150hp (4000rpm) according to its Vehicle Information Kit.

All of those are the gross numbers, not the net.

It is somewhat interesting that your numbers are right in the ballpark for torque (though shift up the rpm band a bit) but a fair bit lower on power.
