I was messing around with the AGP Wastegate today to get it set to 15 PSI again and I think I over did it. So I drive around and floor it, but my Exhaust starts making a Pop Pop sound as I shift in any gear, so I pull over and lower it and still does it and it doesn't go over 15psi. Every time It makes that Pop noise I feel like I'm losing power, what could this be??? Thanks in advance
