Found my first boost problem, ie no boost on second turbo, the culprit, the check valve on the pressure chamber, thing is it was a fairly new check valve, so even new valves can go faulty.
Was this one of the Mazda check valves hamc? i have sets of the ones from america if you get stuck.

No it was the ones from America, i had a spare one thanks for the offer anyway
I have the same problem and Jit has suggested the check valve. i hope it cures it when we have a look this weekend.

If not check the solenoids, i had this prob and was a faulty solenoid.
how do i check them? just out of interest.
Blow job mate! you should only be able to blow one way. one way valves,
so im going to kiss my fd this weekend lol.....i hope it doesnt want to do tongues.
Mine is doing the same thing I think!
Only 0.5 Bar on second turbo?
Where is the check valve? How much do they cost?
What is the pressure chamber?
:)
i had same problem, found it wasnt even the check valve in the end, just a pipe blown off the pressure chamber.

pressure chamber is mid right on the diagram. Its loacted almost exactly in the middle of you engine bay, just behind the strut brace. usually black, plastic, approx 6" across, 2" deep. has 2 small pipes/hoses coming off it.
