Ok so long story short i got a 300zxtt, but it has a bad no boost situation. i checked the wastgate actuators and they crack open at around 15psi, bovs have the stiffest spring so i have no idea what could be wrong other than the plugs are old and getting spark blown out or the turbos are too small? it has sport 500 turbos, 555 injectors, 2.5 czp piping, selin maf translator and thats pretty much it beside the ecu tune.

here is are 3 vids of it.

That video is pretty useless...

If you are not building boost-spark blow out would have nothing to do with that. However too much fuel will cause blowout; but that's not your situation because your engine did not sound like it had a miss in it.

You have a leak in the system somewhere. Either the turbos are bad and there is a leak within themselves or you have a leak somewhere in the turbo system (leaking exhaust, leaking charge pipes etc).

I agree...the video was not that helpful but it does show where the pressure and boost sit...barely. It would be my educated guess that there is a problem with the turbos themselves. If you indeed had your foot to the floor like it sounded you did...the length of time it took for the RPM's to rise indicate either a slow or blocked flow of air or a burnt up turbo. In addition if your wideband was correct...your burning rich. 10.0 is too much fuel. It should be around 11.1 to 10.9 on WOT. Another indication to my theory your engine is starved for air. Really the only way to check your turbos is to pull the engine.
