my car hit 15.6 psi but will only hold ~ 10 psi so my guess for this is boost leak? the throttle constantly says it is at 12% even with no throttle applied, but this is probably just a calibration issue within the app correcT? i also have two codes which are not throwing anything on the DIM and dont seem to be affecting anything but are stored in my ECU. the torque app says therse codes may be cleard by the ecu itself. what else should i take a look at to make sure everyting is running a-ok. oh also the car hovers at around -11 psi(vacuum) when idling and goes down to -14.6 after coming off of WOT.
