Cold Weather Package
Just get it!I had to bitch and whine quite a bit about the retrofit but ended up getting the to install it for $400. That includes installation of the cable and the programming. Still pricey but I'm always listening to music in the car so I might as well have it sound good

Now my only complaint with the car is the comfort of the drivers seat. I sat in a 5GT when I dropped the car off today, now those seats are comfy and the interior is to die for! Too bad the car looks so ugly on the outside.

For example lets suppose if you push the pedal when the car its stock @ a 45 degree angle in 3 seconds, the rpms would be at 2.
The throttle response being more responsive means, that now at the same angle at the same time instead of being at 2 it would be at 4 rpms.
thus you getting the "feel" of more hp. It lets you peel out a lot more, which is why ppl also think it gives them more hp and torque than what is posted. lol.

It "feels" quicker because of the throttle response being more, well responsive lol.

Once you hit 35 mp\h or so you notice the increase in power.
