If you have the opportunity to run both on a dyno on the same day, you will know for sure if there really is a power discrepancy.

Ya we drive a lot. My dad drives about 50k a year, I drive about 30k. The 2010 is already traded in so now I just have the 2011 so dynoing both isn't possible. The car does run very smooth, smoother than my 2010. It also seems like its as fast in the high RPM, its just in that heavy torque stage in the beginning of the boost that just seems less. I know the 2011 was a face lift year, is it possible the engine mapping is just different?

FWIW - I just did this reset yesterday for grins. And I can tell a big diff off the line now and in overall throttle response. :thumbup:

You may have to take to dealer if you don't want to wait or you can try if this works.

Reset throttle response:

1) Insert the key & push the start button. (Don't touch the brake pedal & don't remove the key at any time)

2) Press & hold the accelerator down for 10 seconds.

3) Without releasing the accelerator push the start button.

4) Release the accelerator.

5) Wait a full 2 minutes.

6) Start the car normally & drive to see if it's more responsive.
