I was watchin' the road and wondering just how long I could keep the
pedal on the floor before I had to dynamite the brakes. I believe that
Scott said the boost got to about 2.25 bar and then fell off to 1.6 as
the result of higher rpms. I went for the brakes at about 125-mph, which
correlates to about 6800 rpm in 4th gear. I don't know how relevant this
is to this thread as the car does have a Stage III IA chip. I might add
that I have never been overtaken by an S4 at these track events and have
knocked off several.
