So I just got the car back. Here are my concerns -

1. The new turbo spool is much louder particularly under WOT off the line until you get to about 3rd or 4th gear. When I bought the car I never really could here the turbo spool up or maybe you guys have noticed this?

2. It appears to be putting down significantly less power off the line. Before the drivetrain malfunction I could barely get a smooth launch without traction control intervening. My buddy with a new 435 says his is the same way, now my car is smooth off the line and even in Sport I can seem to stomp on the car without ever feeling like traction is an issue.

What would you guys do? Are these issues significant or should I give the new turbo some time to break in?
