I typically only monitor trip average and instant MPG. Regardless of whether you attempt to minimize TPS or maximize instant MPG, it has the same result: you only press the accelerator as hard as necessary to maintain desired speed.
wmjinman is right in talking about focusing on how you decelerate. Your goal should be to avoid the brake pedal like the plague. Every time you press it, ask yourself what you just did wrong and how to correct it for next time.
Also agree that the partial grille block is one of the easier & more effective mods.
