Good evening all,

Looking for some advice on my truck.

I have a 2014 2500 6.7L with a fresh delete on it.

I have an MM3 programmer with WARP tunes, EGR delete, Throttle Valve Delete, CCV delete, S&B Cold Air Intake and 5" turbo-back exhaust.

I have run the truck now for two weeks with no issues except for now.

When I put the truck in reverse I get a loping rough idle and sometimes at stoplights it has the same rough idle.

Not sure what is going on with this. I am thinking it might be because I left the CCV filter under the crankcase?

Maybe that needs to be gone since I put the little vertical filter on the outside of the crankcase?

The other thing I have noticed is when I turn the key to the on the position I get a marble-like sound out my truck.

I turn it on and everything sounds fine but when I turn off the truck and get under it to hear where the sound is coming from it seems like the marbles sound is coming from my turbo or the downpipe.

If anyone has any insight please let me know.

I do have a video with the sounds of anyone who wants me to try and post it on YouTube.
