I have a truck that falls in the area of the TSB for low power in lockup. ? is does everyone need this and would I gain from doing it. I don't want to do it if the only thing I gain is increased fuel consumption. But if it will give more power than lets do it. And on the High idle reflash... ... should I get it even though I have never had a prob will it idleing too slow. Don't see how trucks with the same programing could be so different from each other. I have never driven in a truck with either of these reflashes so I don't know if I need it or not. Please enlighten me. Oo.
