white smoke

I have a 7.3l idi, and when you rev it up past 2000 rpm it starts to billow white smoke and backfire. when i say backfire i mean it sounds like unburnt fuel is going into the headers and burning in there. The injectors were just replaced a year ago and have only a few thousand miles on them. I need to figure out whats wrong with this i need it running soon. thanks for the help

I replaced the fuel filter and also tried draining it. I also bleed the lines of any air.

You can have it flow benched, but it will cost... best alternative is find a used one and see if it fixes your problem. Before that though, try filling the filter with ATF, run it into the pump and let it sit for a day or overnight.
