2018 with 100k miles. I've had the tuck for about a month and I noticed that when I pour the coals to it, there is a noticeable chirpy whistle that fades. It only happens at certain RPM/throttle positions. I've got a diagnostic scheduled at the local Ford dealership, but they can't get me in until mid-February. I don't know if it's a boost or manifold leak or something else.I posted on r/Raptor about it and the only comment I got was someone saying "Oh man. I know what this is. Your Raptor has had a hard life." with no further info. Thanks bro. The truck has been serviced at the dealership for all maintenance and is in great shape sans front bumper. Undercarriage isn't scratched up. I don't know how hearing a chirp has anything to do with how it was treated by the previous owner, but I'm all ears.
