Hello hans,
I"ve read all of the other posts to your message, and I'd first like to say DON'T GIVE UP! I know exactly what you're going through, and i totally feel for ya! I've lost SLEEP over why my car wasn't boosting correctly...
...i had VERY similar symptoms, and when i posted on the board about them, i got very similar answeres.
Low boost, slow slow slow spool, no leaks, many parts replaced... almost word for word what you went through.
It turns out, the vacuum line to my fuel pressure regulator wasn't connected. Yours might just have a leak in the line, OR a punctured diapragm. Definately check it out, if you don't know where it is, how to test, or what to do, reply to my message.
When i hooked up the line, i INSTANTLY had my power restored.
Then, to follow up on the situation, i disconnected my battery for a night, to allow the ECU, and DI/APC computers to reset themselves.
Then i left my BPC unplugged for a day and drove it around. I STILL got 6 psi at that point, so i knew everything was "right on schedule"
then today, after months and months and MONTHS of having poor performance,
i plugged the BPC back in, and took it for a test drive.
I get 15-16 psi MAX ALL THE TIME... ALL DAY LONG! :)
miracles do happen, you just gotta hang in there and keep looking.
so, fuel pressure regulator.
Cat MIGHT be clogged... so might intercooler... but...
check the FPR and report back to me, then i'll tell you everything else i replaced/adjusted and the results i got.
