I have my Over-Run on, but I'm still getting this backfiring on the most minute of throttle... IE, in a parking lot, or driving slow down a street with just the lightest of throttle, or very slow LA traffic...
how can i get this to stop popping? i mean it sounds nice when racing around, but not when in traffic... and this is a NICE looking Porsche, not a old chevy farm truck..

Funny, my old Chevy farm truck doesn't do that... 
(It's running an MS3-Pro, of course.)
Can you post a data log and MSQ?
