Unlock the "GT" Spirit Hidden in Your Kia

Movement that inspires... now with the power to match.

Kia has redefined expectation with bold designs and advanced engineering. But whether you drive the head-turning K5, the award-winning Telluride, or the sporty Stinger, the factory tuning is often overly conservative. "Eco-minded" throttle mapping can make your Kia feel hesitant off the line and sluggish when merging.

The Stage 3 "GT-Spec" Performance Module is the upgrade that completes the package. Engineered to optimize Kia’s Smartstream GDI and Turbo engines, this OBDII module eliminates the "dead pedal," smooths out transmission shifts, and delivers the punchy performance that the "Tiger Nose" grille promises.

✔ Wake Up Your Turbo. ✔ Smooth Out DCT Shifts. ✔ Tow with Confidence.

Why Upgrade to Stage 3?

• Unleash the Boost: Safely unlock up to +45 Horsepower and +50 ft·lbs of Torque (on 1.6T, 2.0T, 2.5T, and 3.3L Twin-Turbo engines). Feel a genuine surge of power in the mid-range.
• Fix the "Hesitation": Modern Kias (especially with DCTs) can lag for a second when you step on the gas. We sharpen the throttle signal to make acceleration instant and predictable.
• Telluride & Sorento Power: The V6 and 2.5T engines in these heavy SUVs benefit greatly from the added torque, making passing on the highway and carrying full loads feel effortless.
• Transmission Smoothing: Specifically calibrated to help Dual-Clutch (DCT) and Intelligent Variable Transmissions (IVT) find the right gear faster, reducing low-speed jerkiness.
• Universal Compatibility: Works seamlessly with the entire lineup: Soul, Seltos, Sportage, Sorrento, Carnival, K5, Stinger, and Forte.
• Plug & Play Tech: Installs in under 60 seconds via your OBDII port. No tools, no mechanic, and no voided warranties.

Smart Tuning for Smartstream Engines

Kia engines use advanced direct injection and variable valve duration. The Stage 3 Tuner enhances this tech rather than fighting it.

The Stinger & K5 GT Advantage: These cars have massive potential. Our module optimizes the boost curve to spool the turbos faster, reducing lag and giving you that "pinned to the seat" feeling without needing an expensive custom tune.

For the Commuter (Forte/Soul): It transforms the daily drive by giving you the agility to zip through traffic and merge safely without the engine screaming.

100% Safe & Warranty Friendly

We know you value Kia's industry-leading 10-Year/100k Warranty. The Stage 3 Performance Chip is 100% safe for your powertrain.

No Trace Left Behind: The device operates as a piggyback system. It does not permanently "flash" or rewrite your ECU. If you need to visit the dealership for service or recalls, simply unplug the unit. Your Kia returns to stock factory settings instantly, leaving no digital footprint.

Frequently Asked Questions

Will this work on the Stinger GT (3.3L Twin Turbo)?
Yes! The Stinger GT is one of our best applications. The chip helps the twin turbos build pressure earlier, significantly improving the 0-60 time and mid-range passing power.

I have a Dual-Clutch (DCT). Is this safe?
Yes. Many Kia owners complain about DCTs being "jerky" at low speeds. The Stage 3 chip smooths out the throttle input, helping the transmission engage more confidently and smoothly from a stop.

Does it work on Hybrid models (Niro/Sportage Hybrid)?
Yes. It optimizes the gasoline engine component of the hybrid system. When the gas engine engages for highway cruising or acceleration, it runs at peak efficiency and power.

Is installation hard?
It is incredibly simple. The OBDII port is located under the dashboard on the driver's side (usually near the fuse box). Just plug it in. It takes less than 60 seconds.
