We have over 55 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Thomas J M from Laramie, WY said, "Alright, this is the ONLY chip or programmer available for the 3.8L of many years. It's a in cab module that simply taps into the MAP and TPS sensor...easy enough. BEWARE...do NOT follow the instructions and tap into an accessory port in your fuse panel. Instead, tap directly to your battery or in my case (battery under back seat) the "jump start" post under the hood. If you do NOT do this, you will get check engine lights all the time. The instructions tell you just the opposite...don't do what the instructions say. When hooked directly, the chip works nicely... I like it, and would do it again."
