What Makes Racebox Special
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 :)
