Low boost, high get, way too much fuel please help

Okay I have a 7.3 psd in a 00 ex mods are as follows, 38r ww2, farmers single shot 165/100's, t500, swamps module, 4-5" exhaust, ebpv delete, hydra custom burnt chip, intake, snow perf stg 3 water meth, i think thats it i cant remember for sure. Heres the problem yesterday I was on it hard all was working well then boost just plummeted I am making 13lbs at redline and bellowing black.

Ive checked the following map, turbo, pressurized the charge side no leaks, wastegate isn't stuck open, everything seems to be in order i just have no boost.

Any help would be great thank you!!!

That would be present. Pop your hood, and throttle up in gear, with your foot on the brake. Don't roast your tires, just try to build boost. If there's a leak pre-turbo, the smoke will rat it out.

Unless there's a hole in one of your boots, I'm unsure.

That would cause a dump in boost?

Yes. My truck did the same thing when I was running 160/100's and had the oil side stick open. Being the oil side I bellowed white smoke though. Fuel side would be rollin coal.

Over fuel will cause drag on the turbine wheel.
