18lbs of boost, i call 
That sounds like ricer numbers to me.
The noise, sounds like raw exhaust popping in the exhaust manifold.

I agree with midnight: You've got raw fuel making it into the exhaust and combusting there. You might have water in the ignition coils, wires and/or connectors. What did you use to wash the engine?
Hard to tell from that vid but the engine doesn't sound very healthy either...

Use an automotive stethoscope (or equivalent) and make sure you hear all 8 injectors "ticking" at idle.
You might also want to do a compression test. You may have a burned exhaust valve.
Is the car running properly? You say it "evens out more or less after 3k rpm": Does it feel like it's running on 7 cylinders?

I call it a ricer number because 18lbs of boost sounds cool and if you were making 18lbs of boost you would be in the low 700 hp range, which you are not(dyno sheet need to prove it)
A non-intercooled setup like you have, running "18lbs" of boost, would be a blow torch into your engine. Do you know how high your ITA's would be? At least in the low 300's if not more. Stock N/A temps are around 120, 18 atmospheres with no cooling would be insane.
Why lie on the internet when asking for help? Makes no sense to me.
Have you scanned the computer for any issues?
Am not talking about how much hp I have. am asking for help and am giving as much info about the car ok. I have no reason to prove anything to you, what is that show dyno sheet, who are you to ask me for that look when you come to Miami fl I'll show you and that's when I'll prove to you what it does.

Make sure you don't keep driving the car like this.
There is obviously gas getting into the exhaust and will destroy everything.
To simplify where to look, there is either no spark in a cylinder or a burnt/sticking valve.
