mine does this as well, under heavy load at around 2500-3500 rpm, but just during the initial snap of throttle input. also just one tick, chirp, or what ever you would call it. i thought is was the ac compressor or something. does this sound like what you are hearing? i have a 6mt as well, but i have owned mine since new. i was considering having the dealer take a look at it but wasn't sure if it was normal.
