unknown backfire PLEASE HELP!!!

[99 Camaro SuperSix]

I have had a problem with a backfire in my 99 has done this three different times with two different computers. Each time it sounds and feels like speed bump at 20 mph and bottomed out the car. the it will not start for at least 20 minutes.

I have put on headers with a small leak at egr, cai, descreened maf, air intake lid definned, and pcm for less pcm.

I have no idea what is wrong with this so any help would be greatly appreciated.

Thank you!

Yeah, if you take out the screen it can give your MAF some false reading.
