A tune is a rewritten set of instructions for the engine computer, changing things like fuel delivery, spark timing and shift behavior without swapping any physical parts. 5 Star writes this one for your truck and emails you the file, and you load it with a handheld device you already own.
why this one — At $300 this is the cheapest way into a genuine custom tune here, because you are paying for the calibration only and no hardware. That is also the condition: it assumes you already have a compatible device such as an SCT, DiabloSport or HP Tuners unit, which is a several hundred dollar purchase on its own. No power figure is published for it.
Page states the tune is "dyno developed, street validated, tow tested" and improves "horsepower, torque, throttle response, efficiency, and drivability" but gives no specific numeric figure.
