Infiniti Q50/Q60 VR30 EcuTek Tune | Racebox
Racebox VR30 Custom Tuning — Infiniti Q50 & Q60
Racebox has tuned over 4,000 VR30s and holds the VR30 world record — Qzilla, the quickest VR30 in the world, in any chassis, built motor or not. Every tune is calibrated for your exact car, fuel, and mods, flashed at home from your phone, with 24–48 hour response times and 30 days of tune revisions from your first datalog.
We only quote numbers we actually make on our dyno. Here’s what a VR30 makes at each stage:
VR30 Power by Stage (whp, Racebox dyno)
| Setup | Fuel | Power (whp) |
|---|---|---|
| Stock | — | 270 (non-Red Sport) / 360 (Red Sport) |
| OTS tune + heat exchanger | 93 | 390–410 |
| Full bolt-on | 93 | 420–440 |
| Full bolt-on | E30 | ~470 (the sweet spot) |
| Full bolt-on + port injection | E85 | 490–500 |
| Upgraded turbos (stock motor) | E85 | up to 800 |
Upgraded turbo range on the stock motor: Z1 VRX60 ~700whp, VRX70 ~750whp, VRX80 ~800whp. FBO E30 is the bang-for-buck sweet spot — roughly a 200whp gain over stock on the stock turbos, where the car stays reliable and fun before you hit diminishing returns.
Which tune should I pick?
Match the Tune Type option above to your build:
- OTS (Stock Turbo Gasoline) — stock car with a heat exchanger and basics; plug-and-play, 390–410whp.
- Custom Stock Turbo Gasoline — full bolt-on on 93 octane, dialed for your mods (420–440whp).
- Custom Stock Turbo E30 — the FBO E30 sweet spot (~470whp). The one most people want.
- Custom Stock Turbo E85 — full ethanol on stock turbos (490–500whp with port injection).
- Custom Upgraded Turbo — VRX or hybrid turbo setups, up to 800whp on the stock motor.
The first mod on every VR30 is a heat exchanger, and full bolt-on is lower downpipes + heat exchanger + catback + intakes. Our VR30 Build Guide walks through every stage, part, and cost — read it before you buy and you’ll know exactly which option fits.

The Racemode Advantage
The Racemode Advantage: An Overview
Tailored Performance Calibration for the VR30 Platform: Racebox specializes in custom performance calibrations designed specifically for your VR30 platform, 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 VR30 engines, 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 Q50 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.
- Racebox Launch Control: Experience exhilarating launches with our custom or OTS tuning, designed to deliver rapid 0-60 MPH times.
- 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.
