So I noticed, what seemed to be, a loud clacking/top end rattling noice when rolling into the throttle. I was in 5th gear around 60mph and I rolled into the throttle to get around a car, I didn’t roll into it hard enough or fast enough to get a down shift. The engine lagged a little and I noticed a loud rattling that sounded like it comes from the head, yes it sounds like that typical Diesel engine clacking. Once the engine builds boost and the power comes on the rattle completely goes away. I’m not sure if it’s always been there and I’m just noticing it but now I notice it all the time. I’m fully deleted with drd tunes and 90k miles. Am I hearing something that’s normal? Any of you guys experience this? @DRD
