You know it's funny...on Barry Grant's troubleshooting part of his website, it lists rich idle and popping through exhaust both as a result of high fuel pressure.....it lists some other items, but it seems like high fuel pressure is a common denominator. Since I am pushing close to 8psi, I think I'm gonna order a regulator (the Holley Red fuel pump I have should be regulated at 7, but apparently it's not) and see what that does.
