I just got my car back about three days ago from the dealership after a rather lengthy stay in which they found absolutely nothing wrong with my car. I have left the car running the stock tune. I have been driving it around just in town without a chance to open it up, but something felt a little off. So yesterday I got a chance to really get on it and the car felt incredibly slow. Not to be one to let my butt dyno to define the poor performance, I timed some 0-60 runs and the times ranged from 6.43 to 8.1.
I immediately started to wonder if the vehicle was making any boost and it was confirmed by the Torque app on my phone that it was indeed making boost. Not knowing my ass from elbow with these engines, first thing I decided to do was to make the rear BOV vent to atmosphere. Sure enough that under acceleration from 1/2 throttle to WOT, the entire time that the pedal is pressed, the BOV is dumping what could be all the boost.
Before I head back to the dealership and have them start what will probably be a long troubleshooting session, does anybody have any ideas as to why this is happening?
