996 no boost
 

To the doctor or anyone who knows

i have a 2002 996, the original dme was chipped, i put a new one in to bring the car back to stock. the car is running in a limp mode, no psm, no driving assists, no boost. the pst2 codes are p0102, and 5525. maf was changed and the wires are good. new air filter, no blocked intake lines, muffler and cats are not blocked, a little bit dirty due to limp mode running rich. i am stumped, any help would be appreciated.

Don't know Porsche specific codes but I believe
P0102 is not mfr. specific. On others it is MAF (mass airflow) sensor output low. Bad sensor, bad wires, oil-contaminated sensor (overoiled reusable air filter?), or least likely, a fried computer.
