Maybe you guys will think I'm crazy but I've had both types of PT's, N/A and Turbo. I've also driven several of each model other than mine. I've noticed that the non-turbo PT's have a stronger resonance frequency which has a ringing effect that is excited by certain audio frequencies while listening to music, from certain exhaust note frequencies, and from some chassis, suspension, or interior trim pieces that resonance or ring. Has anybody else noticed this?
