smog pump
I have an 89 dakota sport with a 3.9 yesterday i took the belt off the pulley for the smog pump and i gotta say my truck runs sooooo much better it a lot smoother acceleration and better over all response. It didn't set off the check engine light as i still have everything in place i live in a state that has strict emissions laws so i can't completely gut the system yet but if you have an LA series 3.9 I'd highly recommend doing it if you haven't all ready
