Thanks. I just called them. Here is what I learned.

I have serial number 30, one of the first they ever installed.
There have been several updates to the manual since the version I have;
none of them major.

The basic design has not changed since installation.

They have insufficient data on failure rates, but they have several of
them that have been operating through several engine changes without
failure.

There is a revised operating range (and chart) associated with the
wastegate that I should have.

They are sending me the updates and chart, right away, without charge.

These folks are really on top of their product and have outstanding
customer service. It was a pleasure dealing with them!
