04 gtp weather its cold or warm it sounds the same its a uniformed tick at idle and if you slightly increase idle the ticking gets faste not louder cant really hear it much under load. Tbhis gtp is 100 percent stock it idles smooth and boost is smooth no chugging. About 3 weeks ago i had a reduce engine power warning and stopped vehicle thats when it first started with the ticking. Got any ideas thanks and i will try and post a vid.
