Why you'll love it

Our humble beginnings

Racebox was conceptualized when our founder Hussain Boxwala was trying to purchase a tune for his VR30 powered Q50 back in 2018. When speaking with tuners, he realized that there was a need for clear communication, honest work, and prompt response service. In an effort to create the best customer experience possible, Hussain set out to develop his first Q50 calibration on his personal vehicle.

100% Honest Marketing

Our main goal is to provide customers with the most realistic expectations for their vehicles. This means we'll never lie about the mods on our shop cars, the times they run, or the power they make. We aim to always provide the most information possible, like listing ambient conditions and correction factors on all dyno charts. We're not here to push an agenda, we're here to help you achieve your goals.

World-class Customer Support

There's nothing more frustrating than waiting weeks for a reply from your tuner, which is why we'll never take longer than 48 hours to get back to you. Often times, it's same day replies. We know you value your time, and so do we. We're reachable via phone, text, or e-mail, and we'll never leave you hanging :)

We have answers!

Frequently Asked Questions

Do you tune JB4?

We do not offer any specialty calibration services for the JB4 platform.

Does the tune void my warranty?

The short answer is, it depends. The warranty coverage will range widely from dealer to dealer. The dealership will have to prove your modifications have caused the issue you are bringing it in for. The discretion will vary widely from dealer to dealer. 

From our experience, most dealerships will care more about hardware than a tune. We also provide a stock file to flash before you go into the dealership for work. Our suggestion is also to speak with your local service advisor and see what they have to say.

I am not local to the Houston area. Do I have to visit a dyno shop to get tuned?

No worries! We have customers all over the globe! Many of whom are not near a performance-related shop. All you need is a smartphone and an e-mail account. We have thousands of customers who have never visited a shop or dyno, and are enjoying our performance calibrations. 

What’s the difference between remote street tuning and dyno tuning?

Remote Street Tuning: This option is the most popular among our customers. It doesn’t require a visit to a performance shop or dyno. All you need is an EcuTek Bluetooth module and a smartphone. You’ll perform wide-open throttle pulls on an appropriate road course, and we’ll guide you through the process with detailed instructions and video tutorials.

Dyno Tuning: This involves placing the vehicle on a dynamometer (dyno), which simulates road conditions while the engine runs. Dyno tuning allows for real-time data feedback and is ideal for customers who want quicker completion of the tuning process or to see specific power numbers. However, we may still require a street data log since load conditions can differ between the dyno and actual driving. Dyno tuning usually costs more due to equipment rental fees.

What’s the difference between OTS and Custom tuning?

OTS (Off-The-Shelf): Designed for quick, easy tuning with pre-configured maps. It’s perfect for stock vehicles and comes with two maps (daily and race), basic launch control, and no revisions. It does not support ethanol blends, race gas, methanol, or aftermarket turbos.

Custom Tuning: Tailored to maximize your car’s potential. Custom tuning involves multiple revisions, making it ideal for vehicles with modifications like ethanol blends, high-performance fuel pumps, and aftermarket turbos. This option supports map switching (e.g., low boost, high boost) and advanced launch control. Custom tuning is our most popular choice, offering significant power gains over OTS maps.

What do I need for remote tuning?

For BMW platforms: A Windows OS-based laptop is required for the first flash. Subsequent flashes can often be done using a phone.

For Infiniti/Nissan platforms: You’ll need an EcuTek Bluetooth module and a modern smartphone.

What modifications do I need to tune my car?

None! Many customers enjoy our Racemode calibration even on stock vehicles. Both OTS and Custom mapping options can boost the power of your VR30-powered vehicle in its stock form.
