I have a stock 2017 C7 Z06 M7 w/ Z07. I can get to redline not moving, and a bit beyond, i got scared at 6700. When in gear and accelerating, it shuts me down around 6k. No matter the mode. I tried using the lights at the top of the HUD or track mode, and it's still in the green or maybe orange if i'm lucky, not even near the middle where i would think i should be told to shift and im always about 500 rpms short of redline. I've owned a 04, 07, 08, all Z06 and never been cut off until redline. I understand there might be readout lag, especially in first, tacking up as quickly as it does, but subsequent gears do the same thing. I tried sport mode display for the big tach and verified i'm not near 6500 RPM's. Ideas for resolution appreciated.
