I was wondering if the 04 has the torque management system in it. My friends recently went to the track and one of my friends co-workers had an 04 and said that he was reving the engine really high. When I try power braking I can only get to 1400 rpms. Oh by the way he also has an a4. They told me he was consistently getting times of 8.3 with only cai and headers. I hope to match that since I have my headers ready to install, but like I said earlier I can't get the rpms that high.
