I've had exactly the same experience. Maybe I'm spoiled from racing a Formula
Ford
where the braking force could be modulated wihtout even thinking about it. My
problem with the TR6 boost setup was that I could never modulate it well enough,
and occasionally $moked the tires when I didn't want to. I just changed my car
over
to Tiltons but have not run it yet, of course. Good to hear that someone else
had
the same experience -- I thought I was just losing my edge. Of course, maybe
both
of us are.
