I think you should make sure you have no exhaust leaks. When you downshift and its high in rpms and you ride it down does it pop pop pop a lot?

what octane are you running? Someone mentioned timing, it's starting to sound like that to me. Wrong octane fuel with the timing being moded would cause backfiring especially at WOT or heavy acceleration.
