I have a 06 zo6 with a custom tune. The loaded tune seems fine around town. went to the dragstrip last night, and 3 out of four passes the car fell on its face at WOT. 1st two passes were powershifted. 1st pass the car fell in 3rd gear.
2nd pass it fell in 2nd gear. 3rd gear I lifted when I shifted and the car made a full pass without a problem. Went out for the 4th pass, lifted to shift, and the car fell in 2nd, and woke back up when shifted to 3rd.
There were no no "reduced power" messages in the DIC, and no check engine lights or codes stored.
I have included a log of when I was able to duplicate the problem on the drive home (the problem happened at around 3:24). I did notice that the car backfired and the stopped making power. I also included a screen shot with text added to show the area where the problem occurred.
any ideas would be appreciated
Tony
