What would cause this?
So I'm playing around with the fuel in MS, between like 4-5300 RPMS @ WOT there is a random popping noise coming from what I assume to be the WG dump tube. It's not detonation, I'm thinking it might actually be running too rich and backfiring? The AFR reads just under 11 at WOT

Yea sorry lol it was reading in the mid tens. The WG is a Tail 38mm VTA with about a foot long pipe. It sounds ******* awesome @ WOT. Anyways, I leaned it out a bit, like mid to high elevens, and the problem didn't go away. Now I'm really confused. I have tried making it very rich (like 9:1) and then leanish (didn't go above 13:1 AFR) and it still does it...
