The Racemode Advantage

The Racemode Advantage: An Overview

Tailored Performance Calibration for VQ37 platforms: Racebox specializes in custom performance calibrations designed specifically for your VQ, 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 VQ37 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 of experience. 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 :)

What kind of power are we talking here?

For a VQ37, expect gains of 20-40 WHP and 30-50 WTQ on an OTS tune for stock or lightly modified setups. With a custom tune and supporting mods like headers, intakes, or exhaust systems, your power gains will be even more substantial.

What’s the difference between OTS and Custom Tunes for the VQ37 engine?

The difference comes down to how tailored you want your setup to be.

• OTS (Off-The-Shelf) Tunes:

• Pre-configured maps designed for quick installation.

• Perfect for stock or lightly modified setups (e.g., intake or cat-back exhaust).

• Includes two maps (daily and sport) with basic launch control.

• No revisions—flash it and go.

• Custom Tunes:

• Built for your exact mods and performance goals.

• Supports advanced setups like headers, camshafts, and forced induction.

• Includes map switching (e.g., low-boost/high-boost) and advanced launch control.

• Requires data logging and multiple revisions for peak performance.

Which tune should I choose for my VQ37?

It depends on your setup and goals:

• OTS Tunes are perfect for stock or bolt-on setups where you want quick, reliable gains.

• Custom Tunes are ideal if you’re running headers, forced induction, or chasing maximum performance with advanced modifications.

Can Racemode handle forced induction like turbos or superchargers?

Absolutely. If your VQ37 is running turbos or a supercharger, our Custom Tunes will ensure your setup is optimized for power, reliability, and drivability.

Can Racemode handle ethanol blends like E30 or E85?

Hell yes. If you’re running E30, a flex-fuel kit gets you there. For E85 (anything over E50), we’ll need to upgrade your HPFP, LPFP, and slap on that flex-fuel kit. Ethanol is the cheat code for unlocking next-level power, and we tune it like pros.

Does the tune come with launch control and map switching?

Yes! Custom Tunes include fully adjustable launch control and map switching, letting you toggle between setups for daily driving, sport mode, or full track power at the push of a button.

Do I have to visit the shop for Racemode Tuning?

Nope. You could be in Houston or halfway across the globe—we’ve got you covered. All you need is an EcuTek Bluetooth module, a smartphone, and an internet connection. We’ll walk you through the entire tuning process remotely.

What do I need to get started with Racemode Tuning?

Here’s what you’ll need:

• EcuTek Bluetooth module.

• A smartphone or laptop (Windows OS if needed).

• A stable internet connection.

• Any supporting mods installed before flashing (e.g., headers, intakes).

How long does the tuning process take?

On average, 6–10 business days. How fast we finish depends on how quickly you respond and send logs. Custom tuning is a team effort—don’t ghost us, and we’ll get you ripping down the road ASAP.

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.

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.

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 VQ37 running strong after tuning?

Maintenance is everything. Stick to regular oil changes (use high-quality synthetic only), replace spark plugs regularly, and monitor coolant and transmission fluids. If you’re running a high-power setup, consider adding an oil cooler or upgraded radiators.

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.
