APR Software Upgrades
APR ECU and TCU Upgrades recalibrate your engine or transmission controller to deliver more power, rev higher, shift faster, accelerate faster, improve performance, and improve the overall driving experience. Essentially both upgrades are software that installs on your vehicle’s factory computer. The software controls the way the engine, or transmission operates. These upgrades are commonly referred to as a tune, remap, calibration, chip upgrade, reflash, reburn, or one of several other names. They are among the first modifications you should consider for your vehicles as they deliver the most impactful difference you can feel and measure for the money. Choose a Engine (ECU) or Transmission (TCU) to find your platform.
