I'm a newbie here but OneBadRx7 take it easy on the guy. Its obvious by his sig thats he's in China which means english probably isn't his first language. I admire the fact that he's able to type at all in english, God knows my chinese sucks rocks probably like most of us here.
Jack- Try to find some way to have a compression test done that's the only real way to tell whats happening. With that said, it sounds like the turbos are shot more than anything.
That's my best guess. I'm sure there are guys on the board that surpass my knowledge on the matter and can help you more.
Good luck!

0.73 bars is about 10.5-10.7psi which is what your suppose to be getting, perhaps before you were just over boosting to 0.85 which is near 12.15-12.45psi.
what exhaust system are you using? i think that it might have become stuck if its the stock system.
What other modifications do you have?

On the PFC, what does your vacuum show at idle?
Does your engine vibrate so bad at idle that it shakes the car? How many km on the engine?
Same symptoms as mine.. Boost gauge was showing ~10 of vacuum. Not good.
After taking the engine apart looked like I spewed 4 apex seals!

go to www.mazdatrix.com and get the compression tester (maybe it's called something else) from them. I'm sure they're ship it to Hong Kong as long as you pay the shipping charges. Have you changed all the vaccum hoses? Also, check all your solenoids and actuators and make sure they're all functional. That way, you can eliminate the possibility of those components being the culprits. But I would get that compression tester first though. BTW, which part of Hong Kong you live in? I came here 11 years ago from Happy Valley. I really miss that happy place. Late
