Is my cars engine....a weirdo???

Ok, so last week I went to a local tuner shop and got it dynoed. My results were, out of 2 pulls, 124.4 wheel horsepower and 124.5 pounds of torque. If I remember correctly, the temputure outside was around 75 degrees and the humidiy was 50-60%(?) My only modification is a K and N filter; I even have super heavy cast aluminum rims on the car. Now, my car is rated at 140 flywheel horsepower from the factory, 150 pounds of torque. By this estimate, I only lose LESS than 10% to the wheels?

Oh, here is the dyno sheet:

The writing is hard to read. Its says:

DYNORUN.001 Max Power =124.4 Max TORQUE = 124.5

DYNORUN.002 Max Power =122.8 Max Torque = 126.4

Yea, its your manual transmission that is helping out. A GAGT ( or in my case, the V6 se ) Dyno's at 143.38 whp and a whomping 179.91 ft-lbs of torque ( no bear in mind this is with an extremely dirty CAI, but its pretty similar to a stock GAGT as others have proven ). That just proves, that the ecotec has some power to it ( only about 20 to 25 WHp less than the 3400 ). Its the torque in where it dies, but that is due to the beautiful displacement. As you can see, thats roughly a 16% loss compared to your 10%.
