08 C6 on the street every shift including 3-4 happens when I want the shift to happen. However at the track 90% of the time the 3-4 shift is delayed. The vette dosn't hit the revlimiter and I have all torque managment removed. It just goes up in rpm great and then starts to nose over when the shift should be happening. If I don't get any tire spin on take off it feels better but still not perfect like on the street. I found a large multiple page post on HPtuners about this same problem from many users, with no answer. I know you have the answer for this one.
Thank You
