Hello, I'm fairly new to the community so forgive me of any unintended ignorance.

In November I did I an EGR, exhaust system delete on my 2017 2500 using an MM3 tuner from DRD.

Since, I have noticed that I can no longer hear my clutch fan engaging and when I look at it, it seems to turn slowly not producing much draft.

Has anyone else experienced this and if so what might be the solution.

Thank you.
