Unlock the "N-Level" Performance of Your Hyundai

Smart technology deserves smart performance.

Hyundai has redefined the automotive landscape with bold designs and advanced "Smartstream" engines. But whether you drive a fuel-sipping Elantra, a turbocharged Tucson, or the flagship Palisade, the factory tuning is heavily biased toward economy. This often results in a "dead pedal" feel at stoplights and hesitant shifting from the transmission.

The Stage 3 "K-Spec" Performance Module is the digital upgrade your Hyundai needs. Engineered to bridge the gap between "Eco" and "N-Performance," this OBDII module optimizes the complex electronics of your vehicle to deliver crisp acceleration, smoother shifts, and confident passing power.

✔ Fix DCT/CVT Hesitation. ✔ Wake Up Turbo Engines. ✔ HTRAC Optimized.

Why Upgrade to Stage 3?

• Boost Your Output: Safely unlock up to +40 Horsepower and +45 ft·lbs of Torque (especially potent on the 1.6T and 2.5T engines). Feel a genuine surge when you merge onto the highway.
• Eliminate "The Lag": Modern Hyundais often hesitate for a split second when you step on the gas. We sharpen the throttle signal to make acceleration instant and linear.
• Smoother Transmission Logic: Specifically calibrated to smooth out the jerkiness of Dual-Clutch Transmissions (DCT) at low speeds and remove the "rubber band" feel of IVT transmissions.
• SUV Power: For Santa Fe and Palisade owners, the added torque makes the vehicle feel significantly lighter, especially when carrying a full carload of passengers.
• Universal Compatibility: Works seamlessly with naturally aspirated, Turbo, Hybrid, and N-Line models across the lineup.
• Plug & Play Tech: Installs in under 60 seconds via your OBDII port. No tools, no mechanic, and no permanent modifications.

Smart Tuning for Smartstream Engines

Hyundai’s engineering is advanced, utilizing complex variable valve duration (CVVD). The Stage 3 Tuner uses adaptive algorithms to enhance this tech.

The Turbo Advantage: On 1.6T and 2.5T engines (Sonata, K5, Tucson, Santa Fe), the chip optimizes boost build-up. This reduces the time it takes for the turbo to spool, giving you power in the mid-range where you need it most for daily driving.

For the N-Line & N Owners: It stacks on top of your factory "Sport+" or "N" mode, sharpening the throttle mapping even further for a track-ready experience.

100% Safe & Warranty Friendly

We know you value America’s Best Warranty (10-Year/100k). 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 Hyundai returns to stock factory settings instantly, leaving no digital footprint.

Frequently Asked Questions

Will this work on Hybrid models (Tucson/Santa Fe/Elantra Hybrid)?
Yes. It optimizes the gasoline engine side of the powertrain. When the gas engine engages for acceleration, it operates at peak efficiency and power, blending seamlessly with the electric motor.

I have a Dual-Clutch (DCT). Is this safe?
Yes. In fact, many owners prefer the chip because it smooths out the low-speed hesitation that DCTs are famous for. It helps the transmission engage more confidently from a stop.

Does it work on the "N" Performance models (Veloster N / Elantra N)?
Absolutely. While the N cars are already tuned for performance, this chip acts as a "finishing touch," smoothing out the torque curve and sharpening throttle response in the mid-range.

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.
