So to further back up this thread. I started tuning my roush tvs coyote recently. from the start i had throttle oscillation issues. NOTHING i did helped. adjust torque tables. nothing. driver demand would just move it earlier or later in the throttle. today i licensed a file that txcharlie posted from a roush m6 car and i copied over my current file at the time and problem solved. I'm gonna drive it some more and get confidence back in the car before i report 100% victory but i think its safe to say its gone.
