[QUOTE="RustyNutz, post: 1543622, member: 41042"] I dont know know if it helps, but I noticed my 18' 17k mile make very similar, which I noticed greater after an MPT 93oc tune. I even submitted a support ticket, because at 4500+ rpm, esp in 2nd and 3rd gear, it has a very similar squeak/rattle noise. They looked over my logs and showed everything looks proper. Knock sensor is showing OK, and it seems milder than a knock. I have started to think its a sqeaky wastegate connecting rod, or like you guys say something to do with blowoff/recirc noise. Now I want to test mine in 4a...You've got me thinking it might be something losing vacuum pressure (from being in boost/away from vacuum for so long) [/QUOTE]
