Is it stated in the MSP service manual what the stock boost should be (exact PSI, or at least a range)?

Is that official? I'm having some issues with my dealer and the fact that stock boost is 4.9psi ever since they replaced the turbo for a bad wastegate. They are telling me that there is no problem, but if I know that the service manual, or anything offical from Mazda, says it should be 6.9 psi, then it will help me greatly with some other things.

This goes hand-in-hand with the fact that the turbo has been leaking oil, too.

Shit! 6.9!? I'm only making 6.5. I think I have to give Mazda a call and see what's up.

Seriously, I think the MSP is supposed to be listed as between 6 and 7 psi. But we all know that each car is different.

Again, is there anyone with a service manual that can look to see if there are specific numbers for boost in it? I'd really appreciate it. I don't want this to become a general boost thread. This is very imprortant. Thanks for any help.

Call Mazda.

With all the knowledgeable mechanics on this forum, that's the best answer I can get?

Thursday morning bump.

I still really need this info. I want the numbers from a place that it's in writing, not over the phone from Mazda.

try to pm blkblkzoom (sp). He's a mazda tech.
I think he posted somewhere it is between 6 and no higher than 9.
I'm only like 50% certain it was like that (smoke)
