jsanch21; how do you like the Protomotive 650?? what upgrade are you doing to achieve the 700? what is KW-V3?

 

I feel for you brother. Nothing worse than an annoying little problem that you can't find. Have you checked the suspension? Sometimes the springs, coilovers bind up slightly and makes these kind of sounds. Sorry, I'm no expert. Just trying to think what else it could be.

 

Any update? I am having a similar chirp, but mine does it at startup and sometimes under load

 

me too we must have a bunch of birds trapped chech out my post to compair it's drvin me nuts, mine is very consistant and i never lose boostit chirps from 7 to 1.3 boost. and once only when i start the car, but if i start the car a 2nd time (under 15 min)the chirp is gone wait 15 min and its back????
