Alphaspeed TCU Tune Service - 2012-2016 Genesis Sedan / Equus 8-Speed

Unlock the full potential of your Genesis Sedan or Equus's 8-speed automatic transmission with an Alphaspeed TCU Tune. The factory transmission calibration is conservative by design — Alphaspeed's TCU tune recalibrates shift points, shift firmness, and torque converter lockup behavior to deliver a dramatically more engaging and responsive driving experience. Whether you're pairing it with an ECU tune or running it standalone, the difference is immediately noticeable.
