^^^ Lund. Have Mid throttle issues I experienced on a 4 hour trip I took a few months back. I was needing to pass cars on 2-lane highways without just flooring it. Try to throttle up to 40-50% to get the car just to downshift to 3rd or 2nd gear to get out and around someone and it starts surging or "hunting". Drives great at steady or light throttle and WOT throttle.
