The turbosmart boost controller does seem to have a very smooth arc on the boost guage.
I've been keeping an eye on the pyro

Took it out on some farming back roads and could only
get the pryo to @ 825F. That was at about 120 - 30 kmh but once at that cruising speed the
temps dropped off to about 750F.
I will have to hook up the half cab and head down to the bay!!! There are a few
big long hills on the way which should take it to the extreme.
Anyone else want to chime in?
