Yep, but this happened before I filled with race gas and switched maps too. But the exhaust definitely pops more on race gas, just not as loud and those pops don't sound like it's coming directly from the footwell in the cabin. Thanks for helping, how do you like your Stillen SC btw? I was tempted to get a used kit with the 951 impeller
