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 is B48 Racemode Tuning?

B48 Racemode Tuning is how you take your BMW 340i or Toyota Supra 2.0 from quick to downright mean. Our custom calibration brings out the full potential of the B48 engine, delivering significant horsepower gains, better throttle response, and a smoother, more aggressive powerband. This is the tune for drivers who demand performance that punches well above stock.

Is B48 Racemode Tuning safe for my ride?

Absolutely. We design every tune to maximize performance while keeping reliability in check. With Racebox, you’ll get insane power without putting unnecessary stress on your engine or drivetrain. It’s all about controlled performance.

Which vehicles can run B48 Racemode Tuning?

If your car is running the B48 engine, we’re ready to unleash it. This includes the BMW 340i (with the B48 2.0L) and the Toyota Supra 2.0. If you’re not sure whether your car qualifies, reach out, and we’ll confirm.

What kind of power gains can I expect from B48 Racemode Tuning?

• OTS Tune: Gains of 40-60 WHP and 50-70 WTQ, even on stock setups.

• Custom Tune: Gains of 60-80 WHP and 70-90 WTQ, depending on supporting mods like a high-flow downpipe, upgraded intercooler, or ethanol blends.

What’s the difference between OTS and Custom Tunes for the B48 engine?

The difference comes down to how deep you want to go. OTS is quick and effective, while Custom is a full-on performance overhaul tailored to your specific setup.

• OTS Tunes:

• Pre-configured for stock or lightly modified setups.

• Two maps included: daily driving and sport mode.

• No revisions—just flash and go.

• Custom Tunes:

• Built specifically for your mods and driving style.

• Supports ethanol tuning (E30/E85), upgraded turbos, and more.

• Includes map switching, adjustable launch control, and multiple revisions for precision performance.

• Ideal for drivers looking to max out the B48 platform.

Which tune should I choose for my B48?

• OTS is perfect if you’re stock or have minor upgrades like an intake or downpipe.

• Custom is the go-to if you’re running ethanol, bigger turbos, or want every ounce of power extracted from your setup.

Can Racemode handle ethanol blends like E30 or E85?

Absolutely. Ethanol is the cheat code for serious power.

• E30: Requires a flex-fuel kit and nothing else.

• E85 (E50+): Requires HPFP/LPFP upgrades along with a flex-fuel kit.

Whether it’s E30 or E85, we’ll make sure your B48 is optimized for the fuel you’re running.

Does the tune come with launch control and map switching?

Yes, Custom Tunes include launch control (with adjustable RPMs) and map switching for high-boost, low-boost, and ethanol modes. You can toggle between setups with ease.

Do I have to visit the shop for Racemode Tuning?

Not at all. Our remote tuning process is designed to bring Racebox-level performance to you, no matter where you’re located. With an EcuTek Bluetooth module and a smartphone, you’re ready to go.

What do I need to get started with B48 Racemode Tuning?

Here’s what you’ll need:

• EcuTek Bluetooth module

• A smartphone or laptop (Windows OS for first-time flashes)

• A stable internet connection

• All necessary mods installed before flashing

How long does the tuning process take?

It depends on whether you’re going OTS or Custom:

• OTS Tunes: Same-day turnaround—flash it, and you’re done.

• Custom Tunes: 6-10 business days on average, depending on how quickly you send logs and revisions.

Can I tweak the tune later?

While we don’t include lifetime updates for modifications, you can always pay for a retune if your setup changes. If the changes are minor and within the first month—like adding certain mods we already support—we’ll update it for free. Just reach out, and we’ll let you know what qualifies.

What if I run into issues during the process?

Problems? Not a chance—just solutions. Call us at (832) 786-9038 or hit us up on the email thread you’re already in. Attach your data logs, DTC codes, and any details, and we’ll get it sorted. You’re not alone in this.

Will this void my warranty?

It depends on your dealership, and let’s face it, some are chill, and some aren’t. They’ll need to prove the tune caused an issue to void your warranty. Pro tip: we give you a stock file to flash back before you roll into the service bay. Talk to your advisor and play it smart.

How do I keep my B48 running strong after tuning?

Maintenance is key:

• Regular oil changes (synthetic only, no exceptions).

• Spark plug replacements every 10-15k miles.

• Keep an eye on your coolant and transmission fluid levels.

• If you’re running high boost, invest in an upgraded intercooler to keep intake temps under control.

How fast do you respond?

Fast. We aim for a 24-48 hour turnaround during business days. Custom tunes often see daily revisions unless we’re slammed, in which case it’s closer to 48. Either way, you’ll never be left hanging—no ghosting, no weeks of waiting. That’s not how we roll.

What mods do I need to run Racemode Tuning?

None, technically. Racemode Tuning delivers power gains even on stock setups. But if you want to go all-in, start with an upgraded heat exchanger, free-flowing exhaust, and larger intakes. The more you bring to the table, the harder we can push.

What if I’m new to the tuning game?

First things first: get your car up to date with basic maintenance (fluids, spark plugs, filters). Once that’s dialed in, start with the essentials—heat exchanger, exhaust, and intake. Call us if you need advice—we’ll steer you right.

What if I’m not local to Houston?

No big deal. We’ve tuned thousands of cars worldwide without ever meeting the drivers in person. As long as you’ve got the gear (Bluetooth module, phone), we can bring Racebox-level performance to you.
