I didn't do it the first time I installed it and after about 60 miles or so it really kicked in but prior to kicking in had a little rough idle but that's about it.

I uninstalled it this week before taking the car to the dealer now after a reinstall car seems to have less power and poor throttle response and rough idle. Probably about 60 miles since install.

I disconnected the ecu then reconnected with TC connected and the car would not start. Disconnected the TC car started. Reconnected TC and all is back to normal.

It would seem like you have loose wire somewhere, just double check.

I'm kind of agreeing with you. I'm wondering if I didn't have the TC plugged in all the way the first time.
