This is a soler engineering throttle controller that is in excellent condition. It completely transforms how the car works and feels. It sells for $189 plus tax plus shipping, I am asking $150 shipped to 48 states, savings of over $60.
Correct, this is the best/cheapest mod I have ever done to any car. And as you rightly said, it truly does change the car.I put one of these in my car, transformed it into a whole new car!! Throttle response is unreal now!
I keep mine in SP5 usually, but all the variations are great.
