From what I've read about the DI failure issue, it seems like the people who had that problem were tracking their cars. When racing on a track, you're doing more than just redlining through gears; you're keeping the rpm's high, and through certain parts of a track, likely keeping the car around 7,000 rpm's for an extended period of time before upshifting or heel-toe downshifting.

Simply redlining and then upshifting doesn't appear to be the cause. Constant on the throttle and off the throttle (throttle modulation between WOT and partial throttle) at high rpm's for extended periods of time appears to be the culprit... i.e track conditions.
