Hi guys, I am hoping someone might be able to shed some light on an LS7 I am working on. It is a stock Z06 with a cam and exhaust (customer isn't sure what cam is in the car). At light load around 1500 to 2000 rpm, the timing is jumping around like crazy....about 8 degrees up and down rapidly. I tried zeroing out the torque reduction stuff, but it appears that it is still somehow active. Has anyone else experienced this? I have attached the log.
Thanks
