I'm looking for feedback on upgrading my 997.1 TT tiptronic with a torque converter and valve body upgrade. I have the EVO 775 package and the car currently has a hard time building rpms at take off. What are pros and cons to these transmission changes? I'm looking for great acceleration off the line and still maintain drivability for driving on the street. This will not be a drag strip car ( maybe take to the track 2 times in the future). Thanks for your feedback!
