Description
Superb Mid-Range Punch! Unlock Your Stock Car’s Hidden Power with RaceChip
Ever wondered why similar models from the same manufacturer can feel so different? Often, it’s the motor management software—not the hardware—that limits performance. RaceChip’s tuning technology optimizes this software, safely unlocking the hidden reserves in your engine to deliver a powerful boost in performance without costly modifications.
Manufacturers often leave up to 40% extra capacity in your engine to handle various fuel grades and climates. RaceChip taps into 25% of that reserve, making your stock car more fun to drive with stronger mid-range punch, enhanced acceleration, and quicker response. Even if your car already feels powerful, RaceChip unleashes the next level of performance—giving you the thrill of a tuned car while keeping it simple, safe, and within design limits.
The GTS 5 comes pre-loaded with the optimal map for your engine. With 7 fine-tuning maps, selectable via the Digital User Interface, you can easily customize performance to match your driving style or engine characteristics.
- Maps 1-2: Eco Mode
Maximize fuel efficiency with increased torque for smoother driving at lower RPMs, along with a slight boost in horsepower. - Maps 3-5: Sport Mode
Strike the perfect balance between power and fuel economy. This mode offers a noticeable performance boost while allowing you to assess engine behavior before advancing to higher settings. - Maps 6-7: Race Mode
Experience peak performance with maximum horsepower and torque. Start with Map 5 or 6 to test compatibility before pushing to Map 7 for the ultimate driving thrill.
All maps are optimized for performance between 30 mph and 70 mph, delivering what we call the "mid-range punch"—power exactly when you need it for overtaking, highway driving, or spirited acceleration.

I installed the GTS 5 on my Nissan Skyline V37 a few weeks ago, and it’s like my car has been given a new life. There’s a clear boost in power and responsiveness, and it’s smooth, too. It pulls harder and feels more stable at higher speeds. This is a game changer for me.
