low boost high egts too much fuel help please

i think i posted this in the wrong spot earlier

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!!!

When you say you pressurized the charge side, what exactly was your procedure?

sounds like you blew off or blew up an intercooler boot.

no obvious signs of exhaust leaks on the firewall?

You really want to make something more like this and attach it to the turbo inlet.



All of your symptoms really do point to a boost leak somewhere.
