I've been reading about all sorts of noises about this car and last night around 3k rpm with the boost coming on I got a funny sound "honk!!" coming from the engine. Could it be the dv or something loose but I find this hard to believe for a car with 500 or so miles on it?? I was able to repeat the sound easily.

Any info would be great.

 

Mine first did it at 900 miles.

 

I'm sure somebody'll jump in and give a definite answer, but in all the forums I've followed, every time honk was mentioned, it was said to get some Bailey's and replace the stock diverter valves.
