There is a sensor in the clutch pedal that will cut the spark to the engine if your foot touches it while under WOT. It is apparently VERY sensitive and you CANNOT touch the pedal with your foot while under WOT or the sensor will cut power at 5100 RPM's. The engineers have designed this as a safety measure to keep from over revving the engine. He explained that this a very powerful engine and very expensive to warranty. So they made this safety feature very sensitive. An over revved engine would NOT be covered by warranty. So you must keep your foot off of the clutch until you are about to shift, the slightest of contact with the clutch pedal while at full throttle over 93% depressed will cut the spark and power to engine. You don't even have to press the pedal at all, just resting your foot on clutch pedal in anticipation of next shift will activate sensor and cut power. I wasn't sure I believed them at first because I have had multiple stick shift cars over the years and I am driving the same as always. They said they understood, but most cars are not set up like the ZL1. So I went out and tested the car and put it through multiple hard 0-60 pulls with my foot OFF of the pedal and it never cut power. I tested again resting foot on clutch pedal and bingo, cut the power at 5100 RPM's. He said it was the third known case recently that they have put a data box on and all had the same results. It makes me wonder if it is TOO sensitive? I would like to thank the dealer, GM Field Engineer and the GM engineers who analyzed the data. The were very courteous and determined to get to the bottom of it. Also, Dcosta, on this forum for figuring out the issue before the engineers could confirm. I guess I will need to adjust my driving technique from here on out.

Well, that's a relief. At least it's not a wire bundle rubbing on a belt, collapsing inlet tube, or some other craziness.
