Backfiring on stock tune?

[V-Sicks]

I recently put my xcaliber back to stock tune while waiting for my new xcal2 and tune to come in. So it seems if shift at around 6500 or so, it will backfire and pop small flames out each tip. Sound normal?

I've seen it before mostly with O/R mid-pipes.

Mine too. No worries, just a bit rich.

It did it before I tuned mine. Car's probably running rich.
