A stone Posted December 28, 2019 Share Posted December 28, 2019 Purchased my first mack. It's an 03 rd688s. It's a great truck and super clean, but it's the most gutless thing I have ever driven. The throttle response is horrible. Is there anything I can do to improve this problem. It's so bad none of my drivers will even use it.
