Tuning the Genesis G80 3.3T

What tunes do you offer for the Genesis G80 3.3T?
  • Backend Flash (BEF), $189Perfect for JB4/ProTuner users. We handle fuel, timing, and torque limits while your piggyback controls boost.
  • OTS Full Tune, $299Ready-to-go full tune optimized for common setups. No JB4 required.
  • Custom Tune, $495Fully customized tune built around your mods, goals, and driving style.
  • Kia/Genesis 3.3T Stage 2 TCU Tune, from $395TCU tune for the Kia Stinger 3.3T and Genesis G70/G80 3.3T. Faster shifts, crisper engagement, and shift points dialed in over years of testing — chasing records ourselves and helping our customers set their own. Most people assume flat 6,000 RPM in every gear is the move; it isn't, and we've got the data to prove it. Every tune ships with our win-races shift pattern — the one we run ourselves and the data keeps proving right.
