Question What to do w/ P0299 turbo underboost?

Just lost llot of power with turbo and code P0299 came up on jetta 03 w/alh with 151k. Only thing i did lately is change tranny filter and fluid and cleaned EGR and plastic pipe from intercooler. Wonder if I touch something else or when I reinstalled air filter and box . Wonder what caused that underboost ? Is it ok to run the car with that problem?
