i got a T-28 turbo with internal wastegate. the internal wastegate gets its signal(vacuum/boost line) from the compressor housing. the internal wastegate is not adjustable and is set at only 6psi. here are my questions:

- if i were to raise the boost with my greddy manual boost controller, is it ok if i continue to use the compressor housing to get vacuum/boost signal for the wastegate? or is there other better way?

- where do you connect the mbc? is it between and vacuum/boost line and the wastegate?

 

I believe that the MBC has to between the vacuum source and the wastegate. The way I understand it is the MBC is like a wastegate but for boost...it will gradually open as the boost increases so that the wastegate doesn't see any boost until the MBC wants it to
