Weird noise after installing tuner

[Elkins5150]

I got a 2015 challenger srt 392 I installed the Trinity t2 and pcm and between 1500 and 2500 rpm’s it makes a rattling noise I’ve tried all the tunes and now have reset it and the noise is still there

where is the noise coming from?
Theres really nothing a tune can do to create a noise...

It sounds like the engine or maybe the transmission idk I’m so frustrated with this car I not sure what to o next I messed up when I swapped pcms it already had a pcm from you guys Installed and I didn’t k ow that till I went to swap them I put the new one in tried the tunes and this noise started so I went back to the original pcm the noise wasn’t there at first so I tried one of the tunes on it and the noise came back could very well be a coincidence but I messed up by resetting the pcm back to the way it was only didn’t think about it restring it to the back up it made from the new pcm so now I lost the original tune that you guys apparently did that ran great the only reason I tried the tuner was cause I was getting check engine lights for excessive fuel and it won’t go through deq I thought this would cure that now Igor myself in a mess I think any help would be much appreciated
Thanks
