^^ I Agree, I've got a TCI 3000 Torque Converter and the thing launches amazing. Daily driving is not a problem with it. Only when going to launch will it really effect your car, if your looking for a quicker 60' time then go with it. Really easy to install too if you don't mind dropping the tranny.
