SignUp Now!I curious about the TQ curve. Why is it wavey? Was your truck bouncing? Was the belt slipping on the pulley?
That is the OEM load control activating. It is typical to see it in the lower RPMs, and very common at 3900 RPM. I have not seen it in the higher RPMs without the VSC becoming active, but your combination is a tad different than most.
