Ive got one. I love it. It Makes the tranny shift nice. Not to hard but just enough to like. Im not good with words. But I Love mine. They are reall easy to install. Takes about 20 mins. You just attach the switch to your dash or where ever you want to put the thing than run the wire through the fire wall to your computer. Tap two wires into the computer with splicing conections they give you and your done. Just remeber to give the little control box air; for it gets hot. Youll know what im talking about when you get it. Its not the switch that gets hot but control box about 2ft away from the switch. I left mine dangling infront of the fire wall. Its being hung so it gets plenty of air. It dose not bother me there. It dosnt tuch anything. And also remember to disconect your battery when you are putting the wires into the computer harness. It's really easy. Great Mod for anybody to start on.
