I think you're interpreting the graph wrong Rich. What you're seeing at 2700 rpm is the TT car climbing UP to 400 lb ft and then going higher from there. Just as at 1500 rpm you see the stock car climbing UP to 300 lb ft. The stock ZO6 doesn't just start at 300 lb ft. It starts low, as does the TT car, and climbs from there. You don't think our cars produce 300 lb ft at idle do you? The dyno graph seems to start recording at 1500 rpm too. The eng is producing torque prior to that, you're just not seeing it. Hopefully some of the tuning gurus will chime in with some better info.
