I went with the APR stage one. Here's the performance chart:

It's incredible how much of a difference it made. I knew that it was a pretty significant jump on paper, but I had no idea how much of a difference it would really make behind the wheel.
Stock, the car is not that quick. It'll run a 0-60 in 7.3. Now, I'm running them just under 6.
The most impressive thing, however, is the ability to jump from 50-100 in absolutely no time. It's crazy. If you get on it, you can feel the extra 100 lb ft of torque push you to the back of the seat. Next thing you know, you look down and you're doing 100-110 miles per hour.
Best part is, it removed the governor. Pulled onto a secluded part of our local highway and topped it out at 150.
Not bad for a little 2.0 Turbo, no?
