I know this is an ancient thread but I have one question:

MIN boost is the wastegate setting. In the case of my T25 it should be 7psi.

MAX boost - is this a set value for a given turbo, or is it user-definable?

In other words: I think I've heard that if the wastgate has no vac/boost source, the turbo will simply continue to boost until something, whether it's the engine or turbo, gives up.

The above post makes it sound like 14 psi is the maximum boost for the T25, but I know people (dumb people) have boosted them higher. This makes me think that I can choose my own "max boost" and do the math from there to obtain the boost level I actually want, which is more like 12 psi, maybe even only 10 to start.
