I got mine at ts in 2017. It has always been sluggish. And I cant tell a big difference in high or low gears as far as speed or pull. I will check on the things you suggested. Thanks for the info.
I have a friend that has a friend that has the same make and model as mine with the same problem. He installed a chip to bypass emissions and said it was like day and night difference. Just wondering if anyone else has installed the chip.
