Ditch Cobb?

[Whitepony04]

I have a 2020 all stock with Cobb intake and stage 1 91 tune. KOM at 1.00.
Most times when I get not heavy throttle, I can hear a crackle. It sounds like pre ignition but sounds like it’s coming from rear of truck. (It may be my imagination in the location.).
My knock counts go up ad well. I’m runnin go top tier 91 with some booster in for safety. Anyone else experience this with a basic 91 tune? I’m about ready to go back to stock before i window the block.
