Question 1

What tunes do you offer for the Kia Stinger 3.3T?

Accepted Answer

Backend Flash (BEF), $189: Perfect for JB4/ProTuner users. We handle fuel, timing, and torque limits while your piggyback controls boost. Custom Tune, $495: Your car, your mods, your goals — tuned specifically for your setup. We use your datalogs to build a calibration tailored to your modifications and driving style. Revisions are included to ensure the tune is dialed in and performing at its best. Kia/Genesis 3.3T Stage 2 TCU Tune, from $395: TCU 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.

Question 2

How does the tune get onto my car?
