Most rolling road type dynos mis-state torque because of the gearing that the power goes through, not just losses but you have tested in 3rd, plus a diff plus tyres.
Do the same test in 2nd and 4th and see what I mean. trying to reconcile with a proper engine dyno is pretty much futile, all you can do is take the original figure and say these are the changes, these are the benifits. That is why you need to use the same dyno with the same settings every time, it is a point of referance, nothing else

I did test it in 4th gear,and the torque curve was almost the same except for lower hi-end torque.All this results show that the car has pool mid-range torque.I don't care about torque blow 4000rpm,but torque from 4000-5000rpm is still lower than it should be.
I tested several stock cars.Although the results are a little bit far from official numbers due to drivetrain loss and the inaccuracy of the dyno,the torque curves can still show that all the tested cars can reach their peak torque around 4500rpm.But my car can't on this dyno.
