I just completed the installationm of the Soler Performance throttle controller for the C6.
Holy cow! What an experience! This thing has made my car a completely different machine.
After installation, my wife and I went for a test ride. A word of advance; do not use the Ludicrous mode with your wife (or girl friend with you). I think if I want to use Ludicrous mode, I'll have to be by myself. Otherwise I most likley will use the Sport mode.
If you don't know about the electronic controllers, do some research. If you install one, I will be surprised if you aren't impressed.
