Thanks 750hp for your reply. I mostly drag race, but occasionally get to Palm Beach International for road racing. I don't have much vacuum, would that affect the vacuum modulator? I like the idea of being easy on the street during regular driving, but capable on the track, maybe being able to "set" a launch RPM. Can a C4 be built to do that? What is the size of the C4 compared to the T5?
