X15 noise and lack of power on a hard pull.
I now have a 2018 T680 with a 2017 X15. What I have noticed on a hard pull is it feels like it has a miss Almost like a flat spot on a tire when it pulls down to around 1100 rpms. I can also hear it, it sounds kinda like my ISX did when idling ( timing chin noise I guess ) but much much louder. It has just shy of 300k on it and no codes. I have ran injector tests and they all have good results. Is this a normal feeling for this engine? I take it to the shop this week because it’s under warranty from the place I got the truck but I don’t want to look stupid if this engine normally runs like this.

Hope this makes since. Thanks in advance for any input.
