75mm TB installed on 3.2

[j.fro]

This weekend I installed a 996 TB (75mm) on my 2000 Boxster S. It's not too tricky, but I did have to modify/reroute the hoses from the AOS and the intake tubing. I was only able to get out for a 15 minute drive following the installation. From 4000-6000, the engine spins up much faster and the tires were breaking loose, but from 6000-7600 (Softronic ECU with higher redline) the enigine seemed a little flat. I'm guessing the ECU needs time to adjust to the increased airflow. Has anyone else done this and had the same experience?
