I only have the 996 diagnostic info but I think they are the same for Boxsters.
P0134 is Bank 1 O2 sensor interruption of signal
P0154 is bank 2 O2 sensor interruption of signal
"Not passed" may not mean fail. After the DME has been reset, you need a few drive cycles for all these emission readiness flags to be set. For the SAI readiness to pass, I think the DME needs to verify the SAI at cold start and also when engine is already running. It's possible that you just haven't driven the car long enough for the DME to perform those tests.
Is the CEL currently ON and if so, can your scanner read the current error codes?
I am not in the car at the moment but will get back to you tomorrow afternoon when I have tried the diagnosis again

They were checked by a porsche fitter when I had the work done he said the wiring seems ok he used 2 of his own to check them

The lamda sensors are p0134,p0154 but I don't know the codes for the secondary air vaccum but on my diagnostic it says not passed if that's any help.
