The Racemode Advantage

The Racemode Advantage: An Overview

Tailored Performance Calibration for BMW Platforms: Racebox specializes in custom performance calibrations designed specifically for your BMW, taking into account your unique modification list and preferred fueling options, including 91+ Octane and E-85 compatible fuel systems. For those using Racebox OTS (Off-The-Shelf) calibrations, your modifications are considered within the bounds of pump gasoline (non-ethanol fuels). Our meticulous engine tuning ensures optimal performance, maintaining OEM-level drivability and reliability.

Benefits of Racemode Tuning

  • Enhanced Throttle Responsiveness and Drivability: Leveraging our extensive experience with hundreds of BMW tunes, we've developed a calibration that boosts throttle responsiveness and reduces lag inherent in stock ECM mappings.
  • Rigorously Tested: Our tuning strategies have been honed over years, starting with our personal G80 M3, G20 M340i and A91 Supra test vehicles. Through a combination of dyno testing and real-world scenarios, we ensure our calibrations meet the driving conditions our customers will face, enhancing performance and reliability continuously.
  • Precision Ignition Timing for High Octane Fuel: By optimizing engine timing for high-quality fuel, we extract maximum power safely and efficiently.
  • OEM Safety Limiters Retained: We maintain and enhance OEM fail-safes within the ECU calibration, closely monitoring operation parameters to ensure drivetrain reliability, adjusting fail-safes to protect against the increased power output.

Additional Features

  • Speed Limiter Removal: The ECU's vehicle speed limiter is deactivated, allowing for higher top speeds.
  • Improved Fuel Efficiency: Our calibrations optimize fuel adjustments, potentially improving fuel efficiency with aftermarket intake and exhaust systems. Note: Increased throttle use may offset these gains.

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 :)

Racemode Tuning FAQ

We've curated a list of the most common questions y'all have when reaching out to us. Please see the cards to the right for some of the more frequent ones.

What modifications do I need to tune the car?
The simple answer is none! We have plenty of customers who are enjoying our Racemode calibration bone stock. With our OTS or Custom mapping, we can significantly boost the power of your VR30-powered vehicle even in stock form.

What is the difference between OTS and Custom?

OTS (OFF-THE-SHELF) is geared towards users who want to quickly flash their vehicle and enjoy the benefits of their newly found power. You will see substantial gains on even stock vehicles. This option comes with 2 maps for daily and race use, a basic launch control, and has no implied revisions or customization. Just one flash and you're done! If you are running any ethanol blends, race gas, methanol, or aftermarket turbochargers, this option will not be available to you. 

Custom is geared towards users who want to maximize their car’s potential and are willing to go through several revisions. You typically make 30 + WHP/45 + WTQ over an OTS map. Also, this will include map switching (low boost, high boost, etc.) and launch control. This is by far our most popular option with our customer base.

For custom tuning, E30 can be had with just a flex fuel kit, E85 tuning entails anything E50+ which requires an HPFP and LPFP along with a flex fuel kit.

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 which 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 modifications do you suggest for someone new to the platform?
If you are just getting started, we would suggest ensuring the car is up to date on all common maintenance items (fluids, filters, spark plugs, drive belts, etc.). After that is addressed, we suggest adding an upgraded heat exchanger, free-flowing exhaust system, and larger intake system. If you need assistance with part selection, please give us a call or send us an e-mail. (832-786-9038 or sales@goracebox.com)

If I get stuck, what is the best way to get ahold of you?
If you have an urgent question, please call us at 832-786-9038 (M-F, 9-6 PM CST). Any tuning-specific questions are best relayed via e-mail with an associated data log and any potential DTC codes. You can reply back to your tuner on the most recent e-mail thread.
