5.3/4L60 with mild cam.
Runs and drives great, but there is a slight timing pull when you hammer the throttle.
I've zeroed the burst knock table and reduced most of the other knock retard tables. Scanner is not showing any knock reduction.
Torque limiting has been removed. Another weird thing is I'm getting no data below 60kpa MAP.
I'm at a loss at where to check next. On this log , the first WOT was reduced to around 2400 RPM. I got a TPS DTC, cleared that, then the second WOT it pulled, but with a slight timing dip.
Attached is a log and tune.
