It sounds really good. I don't think you were even redlining in you vid.
Also I know a turbo car allways sounds much better under load
In the video, I was only between 3-5K rpm...

Off the line, its better that the flaps are closed since the turbos need some back pressure to spool faster. I end up opening the flaps, just slightly, as I am approching 70MPH and I feel a big difference as the car is accelerating from that point all the way up. The flaps have provided better high end acceleration that I can feel that wasnt available before.

My car ran 12.4 at 110MPH with only Dinan Stage1. Since then, I have installed Stage2 and the exhaust and I am hoping to get back to the track in NJ on Nov 20. We will see how both of these mods affected my times. I will post the results once I have them.
