Okay, I have reading some of the posts and saw that the best MPG is at peak torque. I checked and Peak Tq is at 1,700 rpm. My truck doesn't have a tach even though it is standard. My question is, can I go to the local Pick-a-Part and pull an instrument dash panel of out another truck (same model and style) and put it in mine? I don't like having a round tach sticking out from somewhere inside the cab. I have a lot of long road trips coming up withing a month or so and want to try and get a tach in before I start.
