turboXs mbc ?
OK tried searching im doing a DIY turbo kit still getting all the parts. My ? is on my turbo off a volvo it has an internal wg and it is set at 7psi stock, I have a turboxs mbc I was told that I can use that to lower the boost down to 5psi but to my understanding of my search attempt it can only raise my boost right. So I noticed on the botton of the wg shaft there are some threads that I can twist up is that to lower the boost or raise it if any thanks any help would be helpful.

Re: turboXs mbc ? (BlUAc)
Your lowest boost will be determined by the spring in the wastegate. You can set the <TurboXS> boost controller to 5 pounds, but the wastegate is not going to open until it gets to 7 PSI...assuming thats what spring is in there.
The reason a boost controller can raise boost levels is because it keeps the pressure signal from getting to the wastegate until a certain level (say 15 PSI), when it hits 15 PSI the boost controller lets the signal flow through and it hits the wastegate, which sees something way over 7 PSI and opens.
I think the threads on the wastgate shaft are to adjust the "load" or "pretension" or something like that. Alof of the guys in the SRT-4 camp adjust them to slightly raise boost levels, but again you are probably going to have a lower limit of whatever the spring is.
