That's pretty common with the 5.9's. It's the way they breathe and the way
the exhaust pulses work. Headers will smooth that out and a better
breathing TB will smooth it out more but you're not going to eliminate it
completely.

So what you're saying is that it backfires when you accelerate? I'm pretty
sure that's a bad sign. Backfiring while your slowing down is ok, but not
when you're speeding up.
