I got my ECU back today. It took 5 minutes to put it back in. I got in the car, turned the key, and everything fired up with no problem.

I've driven the car around a bit. My first impression is that this upgrade is totally amazing. It does for the engine what the sway bars do for the suspension. It's that dramatic. The initial sensation is similar to what you feel when bike riding and someone gives you that big shove from behind. Whoa baby!

The car responds very nicely. There is no hesitation or notchiness in the response. You just press the gas and you fly. You can hear the turbo muscle in a little more than before. Whoosh!

Believe it or not, I have not yet gone beyond half throttle or so. There is just so much power there and I didn't have the runway to play. I've heard others say that half throttle with the upgrade is like full throttle was before. That's how it seems to me as well. For relaxed driving, the car seems to have less need to downshift and requires less throttle.

The exhaust upgrade will go in next month when I receive it.
