Well I finally went out and bought a performance meter for the car to get some baseline numbers. The first thing I did was calculate the 0-60 times, and now I quite disappointed with the results of 7.56, 8.0, and 7.72. I would do more testing but why rub a wound with salt. I performed the tests with DSC inactivated, and noticed the engine hesitated at first when accelerating. I think if I could get rid of this hesitation I would have much better results. I'm currently at over 6000ft above sea level and the car has a k&n filter. I was thinking of taking the car back to the dealer to, since it's CPO'ed, to see if they could fix the problem or is this a known problem with a quick fix? Any help would be appreciated.

Something doesn't sound right there. You should easily being doing 6 to 6.5 sec. and once you got it down you should be in the mid 5's pretty much all the time. Sure your performance meter is working right???

What about a Sprint Booster? Seems alot of people have them and say they eliminate to lag between pressing the accelerator and the car actually responding.

Check your Spark plugs, Oxygen sensors, Exhaust Valve if you have it on stock, Gas above of 91 octane.
Maybe check your chronometer... bring another clock with chronometer mode in your hand while you test and compare the time.
Post again after your checks.
Good luck!
