Everytime I start up the car and start driving it, I hear a distinct fluttering noise coming from the engine. It is very noticeable if I am at 25% throttle from 1000-4000 rpm. After driving for 10 mins or so it would go away. I don't know what the cause of this is, but every single time I start up the car it would do this.

 

I would've said it was an exhaust leak, but if it goes away... who knows. My car fluttered with an exhaust leak.

 

Anyone else have this sort of problem? It's weird, it all of a sudden started happening the day after I upped the boost to 10 psi for a canyon run. I didn't even go above 6000 rpm that night and was very light on the throttle. This sound is really annoying me.
