Overland, awesome vid... what numbers did you get after the stage 3 protune? I think our cars are very similar besides the injectors/pump. Here's mine Video Link:
Ah ha! that would explain why there is boost flutter after installing my EBCS. I thought something was wrong.

Jason, sick video, love the cam under the car as you roll over. I know you were a bit disappointed with the numbers last time, how did you make out this time?
