QWKVX Our Drag & Drive Car
Our VX wagon is one of our primary in-house development vehicles. Built as a real-world test platform, it allows us to refine new calibration strategies, validate hardware changes, and develop performance packages before they’re released to customers.
We’re currently working directly with HP Tuners as part of the CORE ECU testing and development program, giving us early access to new firmware, operating systems, and calibration features. This allows us to test, validate, and provide real feedback before public release.
What we’re testing and developing:
CORE ECU integration for LS-based platforms
Advanced ignition, fueling, and torque management strategies
Nitrous activation control and safety logic
Progressive nitrous ramp tuning
High-load, high-RPM durability mapping
Real-time logging validation for nitrous-assisted passes
Custom OS functions and expanded calibration tables
Why the VX Wagon?
The VX wagon is built specifically for reliable, repeatable development work. It is:
Extremely consistent on both dyno and track
Stable under high load and rapid nitrous torque increase
Compatible with wet and dry nitrous systems
Set up on E85 with precise fueling for nitrous enrichment
Fully integrated with HP Tuners logging for calibration validation
Proven in real competition environments
Proven in Competition – Drag Challenge 2025
In 2025, the VX wagon competed in Street Machine Drag Challenge in the 235B class and finished 10th in the class.
The car performed faultlessly across the entire multi-day torture test — proving the reliability of the engine setup, nitrous system, and the calibration work developed in-house using HP Tuners CORE ECU.
The VX done a PB each day with a best 1/4 mile time of 10.7 @ 126MPH & 1/8 Mile time of 6.8 @ 104mph
This real-world endurance challenge provided invaluable data and confirmed the durability and consistency of our tuning strategies under genuine race conditions.
How this benefits customers
Our involvement with HP Tuners — combined with validation through competition — means customers receive:
Safer, more reliable nitrous calibrations
Controlled torque management for smooth power delivery
Better drivability on and off nitrous
​
Access to the newest tuning features as they are developed
​
Calibrations built on real-world competition-proven data
​
​
The VX wagon continues to be our dedicated proving ground. Every improvement we validate through testing and racing directly improves the performance packages available at Cavill’s Performance.
