About Racebox

Founded in 2018 by Hussain Boxwala, Racebox emerged from the vision to enhance the car tuning experience. While seeking to tune his VR30 powered Q50, Hussain identified a gap in the market for straightforward communication, integrity, and swift customer service. Thus, he embarked on creating his first Q50 calibration, setting the foundation for Racebox.

At Racebox, our core mission is to set realistic expectations for our customers, ensuring transparency in every aspect. We pledge to maintain honesty about our shop cars' modifications, performance times, and power output. Our commitment extends to providing detailed information, including ambient conditions and correction factors on all dyno charts, to empower our clients in achieving their objectives without any hidden agendas.

We pride ourselves on world-class customer support, understanding the importance of timely communication. Our policy guarantees a response within 48 hours, although we strive for same-day replies. Available through phone, text, or e-mail, we ensure you're never left waiting, valuing your time as much as you do. Welcome to Racebox, where honesty and exceptional customer service drive performance.

This was my first time getting a tune done remotely, and Racebox really knows what they’re doing. Alex was able to achieve my desired goals very quickly and efficiently, the car feels smooth and very fast. The customer service was great with communication being even faster than expected. The team was very professional and confident with their knowledge, answering all questions I had before even starting work and offering advice. Overall the experience start to finish was very pleasant and I will continue to work with Racebox!

Racebox is an exceptional shop with exceptional folks! The customer service that I have received has truly been the best that I’ve received from any shop. Mo and team are quick to provide me with guidance if I have any questions and issues. The services performed by racebox for my car were FEMTO unlock and flex fuel. One thing I can say is Racebox truly values you as a customer and will always look out for your best interest! My car is a beast and such fun to drive now! I was worried that there is an issue with my car but upon my request Racebox put my car on a dyno before sending the dme out. Mo was my point of contact and he provided me updates every step of the way! He is great to work with and the folks there are amazing. Phenomenal experience and I will be going to racebox for all my needs. 10/10 would recommend and money well spent!

We've got answers to our most frequently asked general questions. You can find the full blog at the link below or contact us (link opens in new tab/window) for anything else.

How does remote tuning work?

Remote tuning is our most convenient way to get tuned with us for those not local to the Houston area or any of our dealers. Simply put, all you need is a smartphone and an ECUTEK Bluetooth module. 

Purchasing: On our homepage, select the Racemode drop-down menu and your platform (Infiniti, BMW, etc.) to select all the options that apply to your specific situation. An ECUTEK Bluetooth module is required for all remote street tuning. If you have any questions navigating the options on our website, please feel free to give us a call at 832-786-9038.

Preparation: We recommend having all maintenance items up to date prior to performing any data logs. Those items can include oil changes, tires, brakes, other fluids, etc. You will also want to install all of the modifications that you have communicated to us before you flash your car with the first base file made by us. That is especially important for aftermarket parts such as larger 3'' intakes, HPFPs, etc. 

Process: When we send out our first calibration base file, you will receive detailed instructions on how to flash the file and data logging instructions. OTS customers will not receive data logging instructions as they are not required for that tune type. Ideally, you will want to have your battery in excellent shape before flashing and have a battery tender hooked up to the battery during the flashing process. After our data logging process is complete, our tuners will notify you the tuning process is done and ask about adding additional maps. 

How long does the remote tuning process take?

The average remote tuning process can take anywhere from 6-to 10 business days from the moment you receive your ECUTEK kit in the mail. The overall time will depend greatly on your response time and our overall customer volume at any given moment. We strive to stick to our 1-2 business day timeframe for the years we have been tuning. Please consider that weekends and holidays are outside of our quoted times. We work through our mailbox on a first-come, first-serve basis. 

If you have not heard back from us for over three days, please get in touch with us at 832-786-9038.

What are your response times?

We strive to provide a 24-48 hour response window during business days. Often times, if you are working with our tuners on a remote custom tune, you'll be receiving a revision a day unless we are exceptionally busy in which case you'll be closer to 48 hours.

But you'll NEVER be waiting weeks for a reply or a revision from us. We also offer lifelong data-log reviews and are available for general sales or customer service support by phone, email, or text.

What do I need for remote tuning?

For many BMW platforms, you will need a Windows OS-based laptop for the first flash for customers on EcuTek. In most cases, we have the ability to use phone flash afterward and can exchange your Deskey for a phone flash license after the initial flash. 

For Nissan/Infiniti, all you need is a EcuTek Bluetooth module and a modern smartphone. 

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

Our remote street tuning process is about what most of our customers choose to go with. This option's most significant benefit is that you do not need to visit a shop or any additional hardware outside of an EcuTek Bluetooth module and your smartphone! This approach will require you to find an appropriate road course to perform wide-open throttle pulls in various gears that are recorded using the EcuTek mobile app. We will send step-by-step instructions along with a YouTube video you can follow along with. 

Dyno tuning involves placing the vehicle on a dynamometer, essentially a set of rollers that simulate road conditions while the vehicle's engine is running. We then make various adjustments to the tune based on real-time data feedback from the data log. This is geared towards customers who want to complete the tuning process as soon as possible and also want to see what power numbers their car puts down. Another benefit is that we, or the dyno operator, can hear potential problems that may arise when performing dyno pulls. We will still likely ask you to perform a data log on the street as loads can change from the dyno to the street. 

The cost tends to be higher as you need to rent a dyno at your local performance shop or our dyno at our Houston, TX, location.
