2008 Chevrolet Silverado 1500 LT 8Cyl5.3L - Engine
How can I lower my RPMs?
The truck has the economy mode but it only goes to 4 cylinder mode while coasting or going down hill. If I have it set on 70mph the RPMs are about 1900 if I could get it to run at 1500 it would kick into 4 cylinder mode continueously. If I have to lower each gear with a progremmer 5 RPMs thats fine too. I live in southwest Kansas and its flat as hell. Was wondering if there is a way to do it through the computer
