Engine clacking and lag

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

What hp setting do you have you tuner on? Are you running a 12Valve sound tune?

Very likely just a little timing rattle.

That’s about what I run and mine makes similar noise when I get on it a little. I don’t think it’s anything to worry about.

I run the 90HP around town and hear the rattle occasionally. I believe it’s normal.

Yeah I believe so to.

Was just strange how I noticed it one day out of the blue and hadn't noticed it before.
