Random puff sound at idle

[slow poke]

Getting a random puff sound at idle after going catless and currently on lund tune.

Is this a misfire? If so what should I check other than plug?

And is there an I deal plug to go with other than stock?

Thanks

Also have an nguage and it didn't show any codes in the diagnostics

Little more info like what the car is in general might help you get a better answer. Just stock castles with a canned tune?

Yeah stock, catless, Lund 93 tune, drop in air filter

No CEL lights, drives normal

Talked to Alex of at Lund he said they can normally do it at idle

There are no mufflers or resonators on the car, just all 3in pipe. I guess this could allow you to pick up what may have otherwise been muffled before

It sounds normal based on your description.
