Hey Grumpywhizzer,
Quenton's right. The NE upgrade is amazing. I got one from him for my 99 & it's amazing!! I work construction & guys I work with get behind me in their trucks to & from work & clock me. They tell everyone I cruise at 40 mph. & that's not full throttle. It's also very easy to install.
