Update, so I finally received the tuner which comes a day or two behind the intake since they ship from different locations. I messed up at first and didn't select the gear ratio so it was driving like I had 3:05's or something. I realized what I had done wrong because the car shifted funny. So I recalibrated everything according to the correct ratio.

The car definitely feels stronger. The intake itself emits a nice growl at part throttle but at full throttle it changes to a howl almost. It has a sort of high pitched roar that is definitely intimidating to other vehicles. The only thing I've noticed which I don't know if it's normal or not is at idle the rpms needle seems to move around a little as if it had a high idle then it comes back to normal.

 

Might be to help keep the revs high during shifting, I know the GT500's did this type of thing stock.
